I am designing a novel circuit that I beleive has not been constructed yet! No -- I'm just using an exotic switching device for a class E amplifier.
My operating frequency is close to the 160 ham band (my target is between 1 and 2 megahertz).
I have seen multiple designs for bands closer to 80 meters (a few megahertz) that use a 47 uH RF choke on the drain of a mosfet. I will be winding this inductor myself so I would like to optimize this value and determine its effect on the output matching circuit.
I have an LCR meter and I am operating this amplifier at a bandwidth not exceeding 10kHz.
Have a schematic (I see this is for 160m and has a larger inductor):
Do I have to know my load impedance before selecting the RF choke or is that load independent? (as a side note I am using Cree SiC power mosfets because I have a source...)
