US Patent 11177988 Receiver circuits with blocker attenuating mixer

A receiver circuit is disclosed. The receiver circuit includes an amplifier having an input terminal, where the amplifier is configured to generate an RF signal based on a signal received at the input terminal, where the RF signal includes an information signal and a blocker signal modulating an RF carrier frequency. The receiver circuit also includes a mixer configured to receive the RF signal and to downconvert the RF signal to generate a baseband signal, where the baseband signal includes the information signal and the blocker signal modulating a baseband carrier frequency, where the baseband carrier frequency is less than the RF carrier frequency, and where the mixer is further configured to selectively attenuate the blocker signal.
