Device and method for interference resistance in broadband receivers

摘要

A multiband heterodyne receiver, and method, having a source of a received signal, a local oscillator that outputs a local oscillator signal, and a mixer that combines the received signal and the local oscillator signal to generate a combined signal. The local oscillator signal can be adjusted in accordance with a detected jamming signal. A DC filter receives the combined signal and attenuates a DC component of the combined signal so as to output a DC filtered signal, and an analog-to-digital converter receives the DC filtered signal and converts the DC filtered signal to a digital signal.
