Hello everyone.

I am currently working on GaN HEMT, Class F with reference frequency of 3.5GHz (Bandwidth spacing of 20MHz).

I've managed to simulate the system on one tune , obtain the S-param ,design T match circuit and obtained an efficiency of 94%, But now I got stumbled upon how to properly design the resonant circuit, since we have 2 tunes on 3.49 GHz and 3.51 GHz.

The objective is to make the resonance circuit accept 3rd IMD and block 5th IMD using two input tunes.
