Abstract :
In this paper, we present a linearity and efficiency investigation of a GaN MMIC power amplifier (PA) designed for supply modulation, by low-frequency (LF) active load-pull at the drain supply terminal, with the PA operating under RF carrier large signal excitation. The baseband load-pull is performed at frequencies up to 6 MHz while the PA is operating at 10 GHz.
