Abstract :
A new functional model is presented for the accurate modelling of Ka-band solid state power amplifier (SSPA) nonlinearities. The model is shown to describe the AM/AM characteristics of several 28 GHz SSPAs more accurately than existing models such as those of Saleh, Ghorbani and Rapp [1981 and 1991].
