The Polar Express - Efficient SSB Generation
Polar Modulation for the masses We have been working on generating SSB signals using Polar Modulation. Hardware stack: RP2350-Zero MCU board + Fast Si5351 module + TPA3116D2 Mono PBTL module / AP63301. Please see https://github.com/kholia/PolarModulationSSB for more details. The audio fidelity and general quality is ok'ish at the moment but it can only improve from here. We are yet to hookup the amplitude ("envelope") restoration part. Why should Guido, Hans, and FlexRadio folks have all the fun? ;) ...
