Abstract :
An ASIC has been designed to perform functions including digital quadrature demodulation and signal detection on an intermediate frequency signal sampled at 400 MHz in electronic warfare receivers. This performance is achieved through a fully pipelined, parallel architecture implemented on a GaAs gate array. The hardware complexity is minimized by careful cost-performance tradeoffs in the design of the algorithms
