We are a leading supplier of low and medium power RF amplifiers with a strong legacy in wireless and cellular markets and eMetering and CATV applications, including a broad portfolio of low noise amplifiers LNAs based on high-performance GaAs and low-cost SiGe technologies.
Wideband amplifier product offerings include drivers and pre-drivers for Doherty amplifiers, femtocell finals and general wireless gain block with bandwidths up to MHz. These ICs are tunable between class A and AB, supporting power-line network operation from either mains or battery power and offer single supply operation with integrated features. Adjusts audio gain based on control voltage for amplitude modulation, level compression, and synthesizers. Digital VGAs includes solutions with high linearity and high output power across a large bandwidth.

The common TO package is used, with the source connected to the tab. The recommended supply range is Vdc. By studying the specifications, it looks like with correct broadband matching and some operational safety margin we can get close to W output at a voltage of around 45V across a resonably large bandwidth; the aim is to cover 1. Main challenges when designing this amplifier are related to achieving good input and output matching over the entire frequency range as well as maintaining high and flat gain.
Good linearity and a low level of harmonic products are mandatory. As the TO is not a package specifically designed for high-power RF, there are some challenges with thermal design and PCB layout as well. The circuit schematic can be seen below. For input a transformer is used, along with a 33ohm resistor R1 that partially dampens the reactive response and improves input matching.
To achieve this value, a LMHV high voltage linear regulator takes the supply voltage and adjusts it down to a value around V, which is further divided down to the exact value via individual adjustable multi-turn potentiometers.
An external signal can cut off this voltage in order to reduce power consumption when the amplifier is not used. The ohm resistors R2 and R3 provide negative feedback, making the amplifier more predictible in response and improving IMD performance. For a small increase in overall gain, it is worth investigating increasing their value. Matching the output to 50ohm is where the real challenge is. For maximum efficiency across a large bandwidth, transmission line transformers TLT are the best option and the closest transformation ratios possible are or With 50V supply and a transformer, the maximum output power that can be obtained is around W as the theoretical load impedance for each transistor is too high.
With a transformer higher power can be achieved but the matching becomes more critical; the supply voltage can be reduced below 50V in order to improve efficiency, but current needs to be actively monitored and kept in the safe area below 20A in total. For minimal losses, the coaxial cable used in the TLT has to have a characteristic impedance that is the geometric mean of the input and output impedances. I chose TC coaxial cable specifically designed for this purpose, that has 17ohm impedance and uses high quality materials so it can handle high power and temperature.
Choosing the ferrite core for the output transformer is key to achieve the best performance. The first prototype used Fair-Rite ferrite beads material 67 in an attempt to achieve the widest working range possible with best efficiency; this sacrifices performance in the lower amateur radio bands, as below 10MHz there is a significant drop in efficiency.

Later on I have also worked for a company that did air ground technology.
I have a background in power engineering however I currently work in the marketing department of a company and not as an engineer. This balance brings a lot of joy for me. My interest in radio frequency started a long time ago and I enjoy bringing modern contribution to amateur radio. I find it very rewarding to share my results and work on something completely different than during my working day.
Before I had already participated in other challenges, and even won some of them with different projects. So of course I had to participate. It was basically a coincidence and already a month before the competition ended.
So I had a lot of pressure to get everything working the way I wanted it to. It was a busy month — usually I allow more time for those kinds of projects. It was actually my first competition in this area and I had a lot of fun participating. New devices make it easier. For this design, I could find all parts from a vendor, but since it is very different from my previous designs, it took me a bit longer to do it all together.

First I built a prototype and after I got it to work I had a board made, which took me about a week or two. However when I found out about the contest it became very clear to me that I wanted to pursue and perfect my idea more.
I wanted to present the technology while keeping it short, easy and entertaining in a way. Usually videos about amplifiers that you can find on the internet are longer and boring, if you are not specifically interested in those kinds of things.
I really like that it uses more affordable NXP parts that work over a broad range. This is probably a very unique part about it.By building this facility and tapping key talent in Arizona, we are able to bring focus to GaN technology as part of driving the next generation of 5G base station infrastructure.
With 5G, the density of RF solutions required per antenna has exponentially increased and GaN power transistors have emerged to address this market, delivering significant improvements in both power density and efficiency.
The fab is set to ramp quickly with NXP leveraging its Chandler-based team's expertise in compound semiconductor manufacturing. NXP engineers will be able to rapidly develop, validate and protect inventions for current and future generations of GaN devices, resulting in shorter cycle times for NXP GaN innovations.
