Abstract :
An integrated circuit has been designed to perform signal processing functions including digital quadrature demodulation on a sampled intermediate frequency signal in electronic warfare receivers. A -3 dB bandwidth exceeding 80 MHz is achieved using a fully pipelined, parallel architecture implemented on a GaAs gate array.<>
