摘要：A radio frequency (RF) integrated circuit (IC) includes a local oscillation module,analog radio receiver, analog radio transmitter, digital receiver module, digitaltransmitter module, and digital optimization module. The local oscillation module isoperably coupled to produce at least one local oscillation. The analog radio receiver isoperably coupled to directly convert inbound RF signals into inbound low intermediatefrequency signals based on the local oscillation. The digital receiver module is operablycoupled to process the inbound low IF signals in accordance with one of a plurality ofradio transceiving standards to produce inbound data. The digital transmitter is operably

coupled to produce an outbound low intermediate frequency signal by processingoutbound data in accordance with the one of the plurality of radio transceiving standards.The analog radio transmitter is operably coupled to directly convert the outbound low IFsignals into outbound RF signals based on the local oscillation. The digital optimizationmodule is operably coupled to the local oscillation module, the analog radio receiverand/or the analog radio transmitter to optimize performance of at least one aspect ofthe local oscillation module, the analog radio receiver and/or the analog radiotransmitter for the given radio transceiving standard being implemented.
