Best Partner for Wireless Modules: A Comprehensive Antenna Selection Guide

n the field of wireless communication, antenna selection is crucial. It not only affects the coverage range and transmission quality of signals but also directly relates to the overall performance of the system. Among various wireless modules, finding the right antenna can maximize their potential, ensuring stable and efficient data transmission.

When designing wireless transceiver devices for RF systems, antenna design and selection are essential components. A high-quality antenna system can ensure optimal communication distances. Typically, the size of antennas of the same type is proportional to the wavelength of the RF signal; as signal strength increases, the number of required antennas also grows.

Antennae can be categorized as internal or external based on their installation location. Internal antennas are installed within the device, while external antennas are mounted outside.

In situations where space is limited or there are multiple frequency bands, antenna design becomes more complex. External antennas are usually standard products, allowing users to simply select the required frequency band without needing additional tuning, making them convenient and easy to use.

What are the main types of antennas?

External Antennas: These antennas can be classified into omnidirectional antennas and directional antennas based on the radiation pattern.

Internal Antennas: These antennas refer to antennas that can be placed inside devices.

Omnidirectional Antennas: These antennas radiate signals uniformly in the horizontal plane, making them suitable for applications that require 360-degree coverage, such as home Wi-Fi routers and mobile devices.

Directional Antennas: These antennas have a high emission and reception strength in one or more specific directions, while the strength is minimal or zero in others. Directional antennas are primarily used to enhance signal strength and improve interference resistance.

PCB Antennas: These antennas are directly printed on the circuit board and are suitable for devices with limited space, commonly used in small wireless modules and IoT devices.

FPC Antennas: FPC antennas are flexible printed circuit antennas that are lightweight, efficient, and easy to integrate.

Concealed Antennas: Designed for aesthetic purposes, concealed antennas can be hidden within devices or disguised as other objects, making them suitable for applications where appearance is important without compromising signal quality.

Antenna Selection Guide

When selecting the appropriate antenna for a communication module, it's essential to first determine whether to use an internal or external antenna based on the module's structure.

External Antennas: These antennas offer high gain, are less affected by the environment, and can save development time, but they may take up space and impact the product's aesthetics.

Internal Antennas: These have relatively high gain and are installed within the device, maintaining a clean and appealing exterior.

Sucker Antennas: These provide high gain and are easy to install and secure.

Copper Rod Sucker Antennas: Made from large-diameter pure copper radiators, these are highly efficient with a wide bandwidth.

Rubber Rod Antennas: Offer moderate gain at a low cost.

Fiberglass Antennas: Suitable for harsh environments and ideal for long-distance signal

External Directional Antennas

Typically used in environments with long communication distances, small signal coverage areas, and high target density.

Panel Antennas have high efficiency, are compact, and easy to install, while considering the impact of gain and radiation area Yagi Antennas offer very high gain, are slightly larger, and have strong directionality, making them suitable for long-distance signal transmission; however, attention must be paid to the antenna's orientation during use

Internal Antenna Selection

Most internal antennas are affected by environmental factors and may require custom design or impedance matching

Spring Antennas are cost-effective but have low gain and narrow bandwidth, often requiring tuning for good matching when installed Ceramic Patch Antennas occupy minimal space and perform well, but have a narrow bandwidth

AM-Detection -the not easy way

Sometimes quite simple things can be a real nightmare if you take a closer look. One of those is AM detection. Your worst enemies are distortion and fading (the latter results in the first). The AM-Detector is only one little part in a receiver, exactly that kind of part usually no one thinks about. "It works, so what should be wrong with?" -a lot and sometimes there's more wrong than right.

A good part of that distinctive AM-Sound we all know is because of the Detector, even under the best conditions. If you're listen to shortwave or the broadcast band during the night then you also have to cope with Fading. Shouldn't be that problem, the automatic gain control takes care of that, right? Ehmmm... Yes. Sometimes. Why the sound gets so distorted when the signal goes down? Just because it's very often 'Selective Fading' and not just Fading -and your Detector doesn't like it.

Really good AM-Reception has a lot in common with High-End-Audio: if it shall work well EVERYTHING has to be well. So let's just talk a bit about Detectors...

Basically the Detector just splits the Audio Signal from the received and amplified Signal. Sounds easy and in fact it is -up to some degree. If you want more than this things getting complicated -really complicated. In at least 999 out of 1000 AM-Receivers for the Detector a small circuitry called 'Envelope Detector' is used, it's just a small Diode (Tube or Semiconductor), a few Resistors and small Capacitors. So, from the view of the Development Engineer: just put half a dozen cheap Components together and Bob's your Uncle. To tell the Truth: compared to the expense that thingy works surprisingly well. Because of this it's the 'Gold Standart' for this task since at least the mid 30s. But as good as it is, it absolutely has it's Limitations. Up to about 15...30% Distortion at a 100% Modulation Level is one, the inability to detect a signal with different sidebands (>selective Fading!) properly another.

To overcome these Limitations a thing named 'Synchronous Detector' was developed many Decades ago. This kind of Circuit has many advantages over the Envelope Detector, but to make one the complexity and the component count of those is just hilarious compared to the Envelope Detector. If only the result counts and nothing else: that's the way to go. We'll talking later how this exactly works, but before this you have to know that in a receiver with a Synchronous Detector also an Envelope Detector is needed: just for tuning in. So first we'll have a closer look how we can get the most ideal Envelope Detector.

Basically it's quite simple: want to have low overall Distortion? Feed it with at least 'a few' volts RF at it's input for having a high ratio between the input voltage and the 'forward voltage' of the Diode. Want low Distortion at low modulation levels? Use a Diode with low Impedance and a load Resistor with a value as low as possible. Want low Distortion at high modulation levels? Just make the input Impedance of the following Stage as high as possible for having the highest possible Ratio between the Resistance of the Load Resistor and the input Impedance of the following Stage.

The Receiver i wanted to use (R+S EK07) has an IF output, meant for exactly such things, the IF Level there's about 250mVpp @ 300kHz. So having everything above in mind -and just adding a 700mVpp IF output for the Synchronous Detector and an additional AGC-Circuitry, then we're coming to this:

The EK07 is a fully tube equipped receiver, so i also want to use tubes as far as possible and -like in the EK07- in a way which guarantees 10k's of Service hours. If at one point a Semiconductor may perform muuuch better -ok, so then. First of all i want high performance. So what tubes may perform optimal here?

For the first IF-Amp (IF1) not much is needed, the Gain is only about 3, the output voltage low and besides that it has to be an remote-controlled type. Selectivity isn't needed or desired, so no IF-Can, only a Broad-Band setup. Nearly every IF-Tube with a Transconductance of at least about 3000mhos (3mA/V) would do that job. To have better performance i took the EF805s, which is a Special Quality Version of the EF85 -or 6BY7.

Transconductance is about twice what's needed, so we'll have Gain to spare, anyway, it's getting controlled with the AGC so it will work with less current which adds greatly to the service life. So no problems here.

For the second IF-Amp (IF2), things aren't exactly that easy. First: the output for the Synchronous Detector is placed between both Amps and has to deliver a constant voltage, so for the 2nd IF we need an Amplifier with an fixed Gain. A STABLE fixed Gain over long time periods. Further we want to have a relatively high and undistorted output voltage which calls for quite a bit of gain. Wait: there was also that thing with the low-value Load Resistor in the detector itself -so we also need a quite reasonable amount of output power from this stage. In Addition we want to have a stable gain for a time as long as possible. A IF-Tube like the EF805s could also handle this, but then we have to 'beat the crap' out of this thing. Not a good start for a long and stable service life, also not with Special Quality Tubes.

Because of all that my choice was a kinda 'special'-Special-Quality type: the E81L.

The datasheet calls this a 'Long range, Special Quality Tube for the use in Telephone Equipment'. Telephone Equipment? Like an answering machine?? Nope, by far not. Back in these days telephone companies needed to have Amplifiers for pushing the calls through loooong cables for long range service. But: this was all multiplex service, so they pushed dozens and dozens of calls simultaneously through one pair of wires or a Coax. The same way like for cable TV. THIS was these bulbs were meant for. For this task every company employed tens of thousands of such tubes 24/7/365. If a single one failed -most likely somewhere in nowhere of course- they had a problem. So they absolutely had to last.

These little bulbs are designed for about 4.5W plate dissipation at 20mA, the Transconductance is 11000mhos (11mA/V)-so it's about twice an usual IF Tube in every respect. So that's exactly what's needed here: a tube especially designed to last, quite powerful, so we can drive it with comfortable low settings, enhancing service life and stability much further.

Because we need some amount of power the usual Broad-Band Amplifier arrangement (still: selectivity is not wanted or desired) with just a plate Resistor isn't good here, a suitable inductor works way better here. This has the further advantage that we can build it with a Tab like an Autotransformer -we don't need that much voltage it could deliver with that inductor by far, so this adds further to a good SNR and lower output Impedance. 300kHz trough a transformer? Yep, no problem. Just use the right core. Here it's not a laminated iron core but a ferrite one instead. Cause it's a single-A Amplifier of course we must add an air-gap, preventing saturation.

In a penthode stage the gain depends nearly exclusively on the Transconductance of the tube used, have to much just cut it down. The E81L has a quite high transconductance, about 3 times more than needed -and in the same order than big output tubes like the 6550, EL34 or 6CA7. For cutting that down to the desired level just put a Resistor or Pot in series to the bypass cap of the cathode Resistor. This acts as an series feedback so it also enhances linearity and long time stability greatly. Yap, i thought quite a while about which tube i should use here.

So after all Amplification is done now, we need a Diode for the Envelope Detector. Back in the Octal-Days this was the 6H6 / EB34, later in the Miniature-Days the 6AL5 / EAA91, both with two separate diodes in one bottle (or Can for the 6H6). These were not A DIODE, these were THE DIODE, so there's not much to choose from. Both are kinda close to each other, but are these ideal for what we want? They both can handle a reverse voltage of several hundreds of volts, so waaaay more than we need here. Both having a Plate Resistance of 600-something Ohms per System which is quite low -could be lower, even with both Systems in parallel. Of course these would be work well, no doubt about. But still.... Hey, this should be High-end so we're whining here at a very high level!

Basically we can use EVERY TUBE as a diode: just take the control grid as Anode, the Cathode as what it is and everything else as Shielding. We don't need hundreds of Volts reverse Voltage, nor high current, so also no big Cathode. We only want to have an internal Resistance as low as possible, so a close spacing between the Grid and the Cathode. This calls for a small Tube with a high Gm (or Transconductance) -like the 6AK5 / EF95. Can it handle the reverse voltage we need? Datasheet says 50V, so at least twice of what's needed. So just take one, put some current trough and take the voltage drop. Result: 210 ohms -way less than that what one of the double-diodes would provide, even with both Systems in parallel. Fits very well!

This is the soviet-military version of the 6AK5W / E95F. Special Quality. See these 'trenches' in the bulb? And the microscopic rivets holding the Plate together? The Soviets literally ruggedized the heck out of this tube! Why? Just because they used it widely in their Fighter Planes, ICBM's, Tanks and so on. Doubts about the soviet built quality? Hey, they wanted to win WWIII with them -so: nope. If you ever saw a ruggedized tube: this it is.

After the Detector itself is done, we come to last part of our little contraption: the buffer Amplifier. At the output of the Detector we have the AF as well with the overlayed AGC-Voltage and we want to have an input Impedance as high as possible for the Buffer Amp. Voltage Gain isn't needed -we have plenty of both from the Detector- so we just can use a Cathode Follower for the buffer. Ideally the Buffer should handle both voltages simultaneously, but then the output will be negative with respect to Ground. How to....? Simple: just put that thing between a positive and a negative supply rail. Then the output can swing freely between every positive or negative Potential as desired. Further: we don't need a Grid Resistor! The Grid just follows any voltage swing of the Detector, this also adds to a high input Impedance.

This Circuit will provide us a very high input Impedance, but this is High-End! So: what tube will be the best for? Because of the lack of any Grid Resistor the input Impedance depends now largely on the contact potential of the grid. So we want a tube with low contact potential which calls for a tube with a low Transconductance. Further we want a tube which needs only a low bias voltage for it's Grid, 'cause we'll loose any bias-volt in our AGC-Output voltage. This calls for a tube with an high Gain. Low contact potential and low Transconductance? High Gain?? That's the 12AX7 / ECC83! Ok, it's of course a double Triode, but we still can use the second system for something else -like for the Line-Output Amp. In that Stage there's not much needed so it also will perform well enough there -we're still talking about AM!

So let's put everything neatly together, adding adequate shielding and so on -and we get this:

So now it's time to have a closer look we did everything right. Just put a 300kHz-Carrier in, 100% modulated with a triangle-signal. We should get a perfect Triangle at the AF-Output -if physics are with us. Due to the Triangle Signal any Distortion can easily be spotted on the Scope.

Looks promising! But somehow... Is the beam defocused? Let's take a very close look:

No, it's not. Those are just the very small remnants of the Carrier, so we actually have a look how the Detector works on a nearly 'microscopic' Level. I could take a measurement how much distortion we have left, but the Flanks of the Triangle are perfectly straight, so the Distortion will be really small -like 1% or so worst case. At least for the moment it's not worth the Effort. Compared to the usual 15...30% Distortion at a 100%-Modulation level this works really well, there's no doubt about.

So finally: we wanted to have a Envelope-Detector as good as possible and here we are. Ok, tbh it's better than needed, cause finally the REAL Detector will be a synchronous one. So why i took this that far? Easy: because of mental peace. Now i never have to think about if that part of the whole final thing could work better. As i said before: it's High-End.

Will update you if the next module is ready. But i fear this here was just the more easy part of the whole thing. From now on things may get a bit more tricky...

Twin Famicom (NES model by Sharp)

The Twin Famicom is a video game console system that was produced by Sharp Corporation in 1986 (Juli 1) and was only released in Japan. It is a licensed Nintendo product that combines the Famicom (NES) and the Famicom Disk System into a single piece of hardware.

The essential parts of the Twin Famicom include a 60-pin socket for Famicom cartridges and a socket for Disk System disk cards. The player could switch between the two media types with a switch – cassette "カセット" or disk "ディスク" The Twin Famicom is fully compatible with the NES and can handle accessories made for the NES (e.g. Beam Gun). But there is also an extra port on the Twin Famicom. This allows a 'regular' Famicom to use the Twin Famicom's disk drive.

The original Famicom only has one color combination, and the Twin Famicom was initially sold in two colors: red with black highlights (AN-500R), and black with red highlights (AN-500B). A second version of the system was released in 1987 with a slightly different case design, turbo controllers, and two different color schemes; black with green highlights (AN-505-BK) and red with beige highlights (AN-505-RD).

Like the Famicom, the Twin Famicom uses NTSC but with an AV output rather than an RF modulator[2][3] with an RCA connector for composite video and mono audio, allowing for greater audiovisual quality on TVs and monitors with such inputs. An external RF modulator is bundled with the unit for connection through a TV's antenna/cable input. The two gamepads are hardwired into the console, so they cannot be disconnected.

HDI PCB vs. Traditional Multilayer PCB: What’s the Difference?

As electronic products continue to shrink in size and increase in functionality, designers are faced with new challenges in PCB layout and integration. Two common solutions are Traditional Multilayer PCBs and HDI (High-Density Interconnect) PCBs. Though they serve similar purposes, they differ significantly in design approach, manufacturing complexity, and application scope.

What is a Traditional Multilayer PCB?

A traditional multilayer PCB consists of three or more conductive layers, typically stacked symmetrically with insulating materials (prepreg and core) in between. These boards use through-hole vias to connect all layers and are widely used in industrial, automotive, and consumer electronics.

Standard via types: Through-hole

Layer count: Usually 4–12 layers

Trace width & spacing: Limited by mechanical drilling

Common applications: Power supplies, industrial controllers, communication modules

What is an HDI PCB?

HDI (High-Density Interconnect) PCBs are a more advanced type of multilayer board designed for higher wiring density in a smaller footprint. HDI boards make use of microvias, blind/buried vias, and via-in-pad technologies to achieve compact layouts.

Advanced via types: Microvias, blind vias, buried vias

Layer count: Often 6–20+, including build-up layers

Trace width & spacing: Much finer (can be below 75μm)

Common applications: Smartphones, tablets, medical devices, aerospace electronics

Key Differences

1. Via Technology

Traditional multilayer PCBs rely mainly on mechanical drilling and through-hole vias, which limit routing density.

HDI PCBs use laser-drilled microvias that connect only adjacent layers, allowing finer routing and stacked via structures.

2. Density and Miniaturization

HDI allows more interconnections per unit area, which supports smaller components (e.g., BGAs with 0.4mm pitch).

Traditional PCBs are less suitable for extremely compact or high-pin-count layouts.

3. Manufacturing Complexity

HDI fabrication requires advanced processes like laser drilling, sequential lamination, and high-precision registration.

Traditional multilayer boards follow a simpler, more mature process and are easier to produce in volume.

4. Cost

HDI boards are generally more expensive due to complex manufacturing and tighter tolerances.

Traditional multilayer PCBs are more cost-effective for larger, less space-constrained designs.

5. Signal Integrity

HDI offers shorter trace lengths and better impedance control, making it suitable for high-speed digital and RF signals.

Traditional boards may struggle with signal integrity at very high frequencies.

When to Use HDI or Traditional Multilayer?

Choose HDI PCB when:

Space is extremely limited (e.g., wearables, smartphones)

High-speed or high-frequency signals are involved

You need finer pitch components (e.g., CPU, GPU, DDR)

You aim for thinner, lighter, more compact devices

Choose Traditional Multilayer PCB when:

Size and weight are less critical

The design uses standard components and moderate speeds

Cost is a major concern

Volume production and fast lead time are priorities

Conclusion

Both HDI and traditional multilayer PCBs play important roles in modern electronics. The right choice depends on your application’s complexity, space constraints, performance requirements, and budget. HDI pushes the limits of miniaturization and performance, while traditional multilayer PCBs remain a reliable and economical solution for many mainstream applications.

Understanding the Pogo Pin Connector: Precision, Performance, and Versatility in Modern Electronics

What is a Pogo Pin Connector?

A pogo pin connector, also known as a spring-loaded contact, is a precision-made electrical component used to establish a reliable connection between two electronic devices. Consisting of a plunger, a barrel, and a spring, the pogo pin ensures consistent pressure and secure contact in a wide range of environments. Its unique design allows it to compress and expand, offering durability and stability even under repeated usage.

Pogo pin connectors are the backbone of modular, test, and high-cycle electronic designs, offering seamless and swift connectivity for both temporary and semi-permanent connections.

Key Components of a Pogo Pin Connector

Understanding the anatomy of a pogo pin is crucial to appreciating its performance capabilities:

Barrel: The outer shell, typically made of brass or phosphor bronze, which houses the internal components.

Plunger: The movable head that makes direct contact with the mating surface.

Spring: A high-precision coil spring that maintains consistent force and enables thousands of mating cycles.

Surface Plating: Gold-plated layers ensure excellent conductivity, corrosion resistance, and minimal electrical loss.

Each component is meticulously engineered to maintain low contact resistance, enhance electrical conductivity, and ensure long operational life.
