Abstract

Over the last six years NASA Lewis Research Center has carried out a program aimed at the development of advanced monolithic microwave integrated circuit technology, principally for use in phased-array antenna applications. Arising out of the Advanced Communications Technology Satellite (ACTS) program, the initial targets of the program were chips which operated at 30 and 20 GHz. Included in this group of activities were monolithic power modules with an output of 2 watts at 20 GHz, variable phase shifters at both 20 and 30 GHz, low noise technology at 30 GHz, and a fully integrated (phase shifter, variable gain amplifier, power amplifier) transmit module at 20 GHz. Subsequent developments are centered on NASA mission requirements, particularly space station communications systems and deep space data communications.In addition, more recent programs investigate advanced materials, such as power high electron mobility (HEMT) devices, pseudomorphic (InGaAs) monolithic microwave integrated circuits (MMIC's), and the interface between GaAs MMIC and high speed fiber optic systems.'
