Antenna impedance/power amplifier source impedance measurement circuitry and device operation based thereon

A method for operating an integrated circuit wireless transceiver comprising:

• for each of a plurality of antennas and corresponding applied antenna impedances coupled to at least one Radio Frequency (RF) power amplifier, impedance determination circuitry determining a load impedance at an output of at least one RF power amplifier of the integrated circuit wireless transceiver, wherein the impedance determination circuitry is operably disposed within the integrated circuit radio transceiver and further operatively coupled to baseband processing circuitry to monitor and alter operation of the integrated circuit radio transceiver;
• based upon the plurality of load impedances determined, determining source impedances of each of the at least one RF power amplifiers and altering a transmit path gain level setting to a target setting.

An apparatus of an integrated circuit wireless transceiver, comprising:

• impedance determination circuitry operable to determine a load impedance at an output of at least one Radio Frequency (RF) power amplifier of the integrated circuit wireless transceiver wherein the impedance determination circuitry is operably disposed within the integrated circuit wireless transceiver;
• and
• processing circuitry coupled to the impedance determination circuitry and operable to alter an integrated circuit wireless transceiver path gain and at least one additional operating parameter of the integrated circuit wireless transceiver to compensate for load mismatches based upon the determined load impedance.
