Abstract

One of the most important applications of GaAs FETs is in small signal amplifier components. High-frequency low-noise GaAs FETs are used in phase-array radars, signal processors, space based electronic detection systems, tracking devices, and digital transmitter-receivers. In particular, GaAs low-noise amplifiers are used in communication equipment for the 3.7–4.2-GHz television receive-only (TVRO) band and for the 12-GHz direct broadcast satellite (DBS) band. The DBS receivers represent a large potential market for GaAs components.
