| 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, the transistors
in a circuit thereto include silicon germanium transistors having switching speeds exceeding 100 GHz, thus to provide for
said high speed analog-to-digital converters and reducing the number of IF down-conversion stages.
