Claim:
An integrated radio system comprises: local oscillation module operably coupled to produce at least one local oscillation; analog radio receiver operably coupled to directly convert inbound radio frequency (RF) signal into inbound low intermediate frequency (IF) signal based on the at least one local oscillation; analog radio transmitter operably coupled to directly convert outbound low IF signal into outbound RF signal based on the at least one local oscillation; digital receiver module operably coupled to produce inbound data by processing the inbound low IF signal in accordance with one of a plurality of radio transceiving standards; digital transmitter module operably coupled to produce the outbound low IF signal by processing outbound data in accordance with the one of the plurality of radio transceiving standards; and digital optimization module operably coupled to optimize performance of at least one aspect of at least one of the local oscillation module, the analog radio receiver, and the analog radio transmitter for the one of the plurality of radio transceiving standards, wherein the local oscillation module further comprises: clock source operably coupled to generate a controlled oscillation from a reference clock; and oscillation generating module operably coupled to produce the at least one local oscillation based on the controlled oscillation, wherein the oscillation generating module includes: phase shift module operably coupled to produce a Q component of the controlled oscillation by shifting phase of the controlled oscillation; first divider operably coupled to produce a first divided by two oscillation by dividing frequency of the controlled oscillation by a factor of two; second divider operably coupled to produce a second divided by two oscillation by dividing frequency of the Q component of the controlled oscillation by a factor of two; local oscillation compensation module operably coupled to produce first and second compensated oscillations by compensating the first and second divided by two oscillations in accordance with a local oscillation compensation signal to at least compensate for DC offset within the analog receiver section; first mixing module operably coupled to mix the controlled oscillation with the first compensated oscillation to produce an I component of the at least one local oscillation; and second mixing module operably coupled to mix the Q component of the controlled oscillation with the second compensated oscillation to produce a Q component of the at least one local oscillation.
