RF Signal Conditioning Module for Digital Receiver

A multichannel digital receiver is required for estimating several signal parameters such as instantaneous frequency, pulse width, pulse amplitude, PRF as well as direction of arrival of signals. In this paper, a five-channel signal conditioning module is developed for the multichannel digital receiver that is capable of operating in 160–180 MHz and 750–1250 MHz bands with 40 dB dynamic range at the input (−38 to 2 dBm).
