   A Simple Cheap 50 Watt PA. IRF510 push pull amplifier. I built this amplifier so that I could be heard above the QRN and QRM on 40 meters in the evening. I found I could work stations in about a 200km radius during the day with 5 - 10 watts, but at night I could work no one at all.

   18 cze 2016 · WA2EBY IRF510 amplifier. The WA2EBY amplifier is a famous linear amplifier project published in QST in March and April 1999 by Mike Kossor WA2EBY. As this amplifier can give up to 50W out with 1W drive, it is a perfect pair for my Softrock RXTX amplifier.

   The power output of Si5351A is around 8-10mW (10 dBm). The BS170 based driver circuit amplifies this to ~200mW (23 dBm) for a gain of around 13 dB. The IRF510 finals provide a gain of around 14dB and produce around 5W of RF power. Input drive matters the most in getting good RF output from IRF510.

   23 maj 2022 · Worked perfectly. Pushing the input power up to 30V @ 3A the amp will easily get to 50W into 50 ohms, but I limit the supply to 28V and that seems to keep it around 45W output. Time for an TX/RX switcher. I needed a way to interface the linear with the uBitX.

   13 gru 2020 · Synthesizing from a number of other amateur radio homebrew circuits I have reviewed, I settled on a simple starting point. This is about the simplest possible IRF510-based amplifier I’ve found, and it’s from Experimental Methods in RF Design (EMRFD from now on), figure 2.98. The book says it’s designed for class AB operation (and I’ve ...
