Abstract:
A Radio Frequency (RF) transceiver includes a baseband processor, a receiver section, and a transmitter section. The receiver section communicatively couples to the baseband processor and includes a plurality of tuned RF circuits. The transmitter section communicatively couples to the baseband processor and includes a plurality of tuned RF circuits. In a calibration operation, the transmitter section applies a RF test signal to its plurality of tuned RF circuits. The baseband processor applies a plurality of tuning control settings to each the tuned RF circuit. The baseband processor, for each of the plurality of tuning control settings, measures an output of the tuned RF circuit. The baseband processor selects a tuning control setting for the tuned RF circuit based upon at least one measured output of the tuned RF circuit. Finally, the baseband processor is operable to apply a selected tuning control setting to the tuned RF circuit.
