Demonstration of GaN HEMT MMIC High-Power Amplifier for Lunar Proximity CommunicationsIn this paper, we demonstrate a Ka-band high power, high efficiency, GaN HEMT MMIC based power amplifier for communications from the lunar orbit to lunar surface. The measured results include Pout, Gain, PAE, RMS EVM for Offset-QPSK, 8PSK, 16APSK, and 32APSK waveforms, 3rd-order IMD products, noise figure, and phase noise.
