Updated 630m PA module nearly finished. Uses a pair Silicon Carbide FETs with a 48% on and 52% off drive waveform. Fingers crossed.

Looks good! Do you expect a big performance difference compared to your 4x IRFP250 design?

The 4 x IRFP250 design will produce more power but it needs a high current supply. The SiC can operate from 48V or higher voltages which means easier matching and lower current. Note it's going to be easy to add 2 more SiC FETs if this board checks out OK

Do you have any projects need PCB?
