Patent ID: 7421250

Claim:
An integrated radio system comprises: direct conversion analog receiver operably coupled to produce an inbound baseband signal by down-converting an inbound radio frequency (RF) signal, wherein the direct conversion analog receiver includes: programmable low noise amplifier operably coupled to produce an amplified inbound RF signal by amplifying the inbound RF signal in accordance with an LNA gain control signal; down-conversion module operably coupled to convert the amplified inbound RF signal into an I component down-converted signal and a Q component down-converted signal; first low pass filter operably coupled to filter the I component of the down-converted signal to produce a filtered I component; second low pass filter operably coupled to filter the Q component of the down-converted signal to produce a filtered Q component; first amplifier operably coupled to produce an I component of the inbound baseband signal by amplifying the filtered I component; and second amplifier operably coupled to produce a Q component of the inbound baseband signal by amplifying the filtered Q component; direct conversion analog transmitter operably coupled to produce an outbound RF signal by up-converting an outbound baseband signal; analog to digital conversion module operably coupled to convert the inbound baseband signal into an inbound digital baseband signal; digital to analog conversion module operably coupled to convert an outbound digital baseband signal into the outbound baseband signal; digital baseband processor operably coupled to process the inbound digital baseband signal and the outbound digital baseband signal in accordance with one of a plurality of radio transceiver standards; and digital optimization module operably coupled to optimize performance of at least one of the direct conversion analog receiver and the direct conversion analog transmitter for the one of the plurality of radio transceiving standards.
