A monolithic multifunction EW broadband receiver converter

Abstract

A unique multifunction receiver converter chip, consisting of RF amplifiers, switches, a lumped-element filter, and a double-balanced mixer, has been developed. The chip design employs various circuit design refinements, such as amplifier feedback techniques to enhance stability and repeatability, FET switches to reduce power consumption, and a lumped-element filter to reduce size. The double-balanced mixer topology eliminates IF extraction problems and combines the best performance characteristics of active and passive baluns while employing diode mixing elements.<>
