Abstract

The design, fabrication, and measurements for 44-GHz-band molecular-beam epitaxy (MBE) monolithic power amplifiers are described. A five-stage balanced amplifier provided a linear gain of 15.1 dB and maximum output power of 500 mW at 42.5 GHz. These results may represent the highest power and gain achieved from a MIMIC (millimeter-wave monolithic integrated circuit) in the 44-GHz band. These amplifiers are suitable for 20/44-GHz satellite communications as well as for phased-array radar applications.<>
