Abstract :
Summary form only given, as follows. In this paper, a digital waveform system for evaluating the linearity characteristics of millimeter-wave GaN HEMT devices and MMICs is described. It is capable of generating and analyzing a wide range of waveforms. The linearity performance of a sample Ka-band one-stage GaN/SiC MMIC power amplifier is characterized to demonstrate the capabilities of the system. Performance metrics associated with different waveforms including single-tone, two-tone and digitally modulated waveforms are measured.
