The demand for more bandwidth is creating more commercial applications for the Ka-band. Satellite communications, point-to-point communications, 5G, and military radar are all applications that use or plan to use the Ka-band. The high-power density and high breakdown voltage of GaN-on-SiC make it of particular interest for power amplifiers. This white paper details the design and performance of 28 V, 3-stange, Ka-band, Gan-on-SiC, power amplifier MMIC with high efficiency and low gain.
