Patent ID: 7796683

Claim:
A radio frequency (RF) transceiver comprises: a low noise amplifier module coupled to amplify inbound RF signals to produce amplified inbound RF signals, wherein the inbound RF signals have a carrier frequency within a receive frequency band; a blocking circuit, when enabled, operable to substantially attenuate a blocking signal and to pass, substantially unattenuated, desired receive RF signals; a down-conversion module coupled to convert the amplified inbound RF signals or the desired receive RF signals into inbound baseband or low intermediate frequency (IF) signals; processing module coupled to: convert the inbound baseband or low IF signals into inbound data; convert outbound data into outbound baseband or low IF signals; determine a transmit power level; determine whether to enable the blocking circuit based on the transmit power level; an up-conversion module coupled to convert the outbound baseband or low IF signals into outbound RF signals; and a power amplifier module coupled to amplify the outbound RF signals based on the transmit power level to produce amplified outbound RF signals, wherein the blocking signal corresponds to the amplified outbound RF signals.
