Patent ID: 8755762

Claim:
A radio frequency (RF) receiver comprises: an amplifier stage coupled to amplify an inbound RF signal to produce both a first amplified inbound RF signal and a second amplified inbound RF signal, wherein the inbound RF signal, the first amplified inbound RF signal, and the second amplified inbound RF signal include a desired RF signal component and a blocking signal component generated by a known RF transmitter having a known transmission frequency, the amplifier stage including: a first low noise amplifier coupled in parallel with a second low noise amplifier, the first low noise amplifier configured to amplify the inbound RF signal to produce the first amplified inbound RF signal; and the second low noise amplifier configured to amplify the inbound RF signal to produce the second amplified inbound RF signal; a blocking module coupled to the amplifier stage, wherein the blocking module functions to: generate, based on the known transmission frequency of the known RF transmitter, an oscillation corresponding to a known frequency of the blocking signal component; lock the oscillation onto the blocking signal component of the second amplified inbound RF signal; filter the first amplified inbound RF signal based on the oscillation to substantially attenuate the blocking signal component and to pass, substantially unattenuated, the desired RF signal component; and a down conversion module coupled to convert the desired RF signal component into a baseband or near baseband inbound signal.
