Abstract:
A circuit includes an input terminal for receiving a radio frequency (RF) signal and a noise mitigation circuit coupled to the input terminal. The noise mitigation circuit is configured to detect a low-frequency noise signature in the RF signal and to automatically adjust an attenuation network to filter low-frequency noise from the RF signal in response to detecting the low-frequency noise signature.
