Abstract:
1. A method of operating a transceiver on a system on a chip, the method comprising: configuring a configurable portion of the transceiver to operate in a first mode of operation; transmitting a test tone from a transmitter portion of the transceiver via an antenna coupled to the SoC via a matching network; monitoring the transmitted test tone by a receiver portion of the transceiver to produce a received test tone signal; tuning a tunable capacitor within the SoC coupled the configurable portion of the transceiver across a range of values and determining a signal strength of the received test tone signal at various values of the tunable capacitor, wherein the tunable capacitor is configured to optimize impedance matching of the configurable portion for each mode of operation; and setting the tunable capacitor to a value that produced an optimum received test tone.
