Abstract
A large-signal simulation program for multistage power amplifier modules by using a novel interpolation is presented. This simulation program has the function to make the Load-Pull and Source-Pull (LP/SP) data required for th e simulation. BS using the interpolation, a lot of LP/SP data can be made f rom a small number of measured LP/SP data. The interpolation is based on th e calculation method using a two-dimensional function. By using the simulat ion program, we can calculate the large-signal characteristics depended on frequency and temperature of the multi-stage amplifier module. We apply the simulation program to tile design of the amplifier. The calculated and mea sured results agree well. The accuracy of the presented interpolation is co nfirmed. It is considered that the presented program is useful to calculate large-signal characteristics of the amplifier module.
