Abstract
This paper designs a 20 GHz power amplifier based on a novel model which is the quadratic polynomial expansion of nonlinear scattering function. The novel model is capable of accurately computing the voltage of device under any fundamental and harmonic frequency load impedance changing implemented with Frequency Domain Defined Device (FDD) component in the ADS. Through the new model, it is easy to find out the optimal fundamental and harmonic load impedance. The designed PA achieves a peak power-added efficiency (PAE) of 35.1% and the saturated output power of 21 dBm in PP1010MS EEHEMT operating at 20 GHz.
