Attached is the circuit I built and which I'm trying to get 23dbm or 200 milliwaters of power at the output. Where I have c3 = 200p,c2=50p, and c1 = 47p cause L1 has a reactance of 250ohms and using the resonant frequency formula we get 47p for the tuner cap. Also I have 27 turns on the toroid since I'm using the t37-2 toroid, and have 12 on the secondary since I'm trying to make the 250 ohm look like 50 ohm on the output. With all that said I am not getting 23dbm but 17dbm. Can someone point me in the right direction of my problem.
