A large-signal simulation program for multi-stage 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 the simulation. By using the interpolation, a lot of LP/SP data can be made from a small number of measured LP/SP data. The interpolation is based on the calculation method using a two-dimensional function. By using the simulation 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 the design of the amplifier. The calculated and measured results agree well. The accuracy of the presented interpolation is confirmed. It is considered that the presented program is useful to calculate large-signal characteristics of the amplifier module.
