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...
In the design of high frequency power amplifiers, the goal is to achieve the power gain and output power at the desired frequency in order to achieve high PAE. Large-signal S-parameters of power devices are normally not provided by the manufacturer. One of the methods to characterize the device...
