Multifunction receiver-on-chip for electronic warfare applications
First Claim
1. A flexible multi-function broadband receiver system for use in electronic warfare on vehicles having weight, size and power consumption limitations, comprising a receiver-on-a-chip having components monolithically formed on a substrate to provide a single integrated circuit chip for performing broadband signal detection using high speed analog-to-digital converters, at least one down-conversion circuit, a digital automatic gain control circuit, a digital signal processor for defining receiver function and a serializer all located on the single chip, whereby modularization is avoided and wherein size and power consumption are minimized.

Abstract
What is provided is a receiver-on-a-chip comprising a monolithic integrated circuit that reduces the receiver to a cigarette-pack-sized assembly mountable directly at an antenna element, with a much-increased operational bandwidth and instantaneous bandwidth, increased dynamic range and with a two-order-of-magnitude decrease in size and weight. Moreover, because of the elimination of all of the I/O drivers and attendant circuitry, power consumption is reduced by two-thirds, whereas the mean time before failure is increased to 10,000 hours due to the robustness of the monolithic integrated circuit and use of fiber optics.
