20m SSB Amplifier
I thought I do a video showing show experiments I have been doing for a 5W push pull style amplifier at 14 Mhz. Charlie Morris has a great video explaining the math here https://www.youtube.com/watch?v=CtyabG69d4g&t=1503s The push/pull style amplifier is based on the Ensemble RXTX power amplifier described here http://www.wb5rvz.org/ensemble_rxtx/10_pa The ltspice circuit is on my github repo. For those without LTSpice the file "Amplifier.png" contains an image of the circuit https://github.com/thaaraak/ltspice Note that the original ensemble amplifier sets the bias of the mosfets using a reference circuit which I did include in the ltspice model - but I used a simple 5V regulator in mine. Here's the site that I used for the lowpass filter https://rf-tools.com/lc-filter/ and the Toroid calculator is here https://toroids.info/T37-6.php
