Abstract
In this paper the MMIC technology, design and characterization of a high power amplifier and driver amplifier MMIC at 30 GHz in AlGaN/GaN HEMT technology are presented. The MMICs are designed using CPW technology on a 390 µm thick SiC substrate. The measured small-signal gain of the driver is 14 dB at 28.5 GHz and the measured output power is 28.6 dBm at 28 GHz. The power amplifier shows a measured small-signal gain of 10.7 dB at 25.5 GHz and output power of 34.1 dBm at 27 GHz. Both MMICs have a very good yield and performance for a first iteration design.
