Hello folks,
I meet problem with designing the loading network for my amplifier. I refer to the paper "Class-F amplifier loading networks a unified design approach" written by Christ Trask(attached), but cannot get the expected result when doing simulation.
The matlab code is as follows:
W0=11.55e9;
BW=1.3e9; %%bandwidth 10.9-12.2GHz
RL=50;
alfa=(W0-pi*BW)/W0;
C1=alfa/((1-alfa*alfa)*W0*RL)
L1=1/(W0*W0*C1)
L2=160*L1*RL*RL/(81*((9*RL*RL)+(4*W0*W0*L1*L1)))
C2=1/(9*W0*W0*L2)
C3=8*C2
Could anyone point out the mistake I made or give me some hint for a new method? Thx in advance.
