I am trying to design an amplifier using CFY6608 [SIEMENS] in ADS. But I have not used this software before. I have the .s2p file. I have to do stability analysis separately using Data Items option, because s parameters are not available with the built in model I think. How can I perform stabiity analysis using bias network in this case?
secondly, to design input and output matching circuit, is there any guidance available? for a particular gain?
