Three channel IF multiplexers

摘要

The first integration of multiple IF functions, into highly integrated GaAs monolithic microwave ICs (MMICs) for electronic warfare applications is described. The IF functions include amplifiers, switches, and attenuators combined into three-channel IF multiplexers. The multiplexers provide a three-channel selectivity and variable gain in each channel for application in wide-bandwidth, high-dynamic-range electronic warfare receivers.
