I am desigining a LNA circuit and have done the input matching circuit as well as the biasing circuit.. I am now currently on the output matching circuit.
The output impedance of the biasing circuit (input to the output matching circuit) is at 63.1-j63.4 ohms and Im matching it to a 50 ohm terminating load.
I am currently using a LC network to match the output as well as to resonate the stray capcitance from the output of the biasing circuit.
I cant seem to find a good compromise between the S11 and S22 parameters and would like to enquire whether using the LC topology is the best choice for this purpose.
Opinions on this would be highly appreciated. THanks=)
