Abstract :
Design and test results are presented for several multiuse GaAs ICs for radar and electronic warfare (EW) applications. The chips described are a redundant switch, a broadband distributed amplifier, a broadband variable-gain amplifier, a 2.5-GHz sample and hold, a 1-GHz analog-to-digital converter, and an L-band buffered prescalar. These ICs, fabricated with the ITT 0.4-μm-gate MESFET multifunction self-aligned gate (MSAG) process, demonstrate excellent performance
