Due to its superior material properties, AlGaN/GaN HEMT power amplifiers offer excellent capabilities, such as high efficiency, ease of matching and broad bandwidth. In this paper we report our initial development of AlGaN/GaN HEMT on GaN/SiC epi-materials. The 10mm gate-periphery device showed 40W CW output at 1.75 GHz, 12.6db liner gain and over 80% drain efficiency with a drain bias of 28V.
