Abstract:
A microwave radio receiver includes a first down-converter, a second down-converter, and a combined receiver signal level (RSL) and interference detector. The first down-converter is configured to convert a RF signal into a first IF signal. The second down-converter is configured to convert the first IF signal into a second IF signal. The combined RSL and interference detector is configured to determine one or more RSLs and generate an interference indicator based on the first IF signal from the first down-converter and a control signal from the second down-converter.
