Design of a 3.5 W S-band Power Amplifier Based on Small-signal S-parameter Analysis

Large-signal device S-parameters are usually used in power amplifier (PA) designs to obtain the desired output power. The large-signal characteristics of a power transistor can be accurately extracted from load-pull measurements as described in the lit...
