Apparatus and method for antenna matching

An apparatus, comprising:

• A transceiver;
• An antenna;
• a tunable matching circuit that is responsive to a tuning input to select an impedance transform of the tunable matching circuit, wherein the tunable matching circuit couples the selected impedance transform between the transceiver and the antenna;
• A cable connector;
• a sensor that determines a cable connection state of the cable connector, the cable connection state being one of present and absent, and generates a cable detection signal that indicates the cable connection state;
• and
• A processing system coupled to the cable detection signal and the tuning input of the tunable matching circuit, wherein the processing system tunes the tunable matching circuit in response to the cable connection state.

A method, comprising:

• Determining a cable connection state of a cable connector;
• Generating a cable detection signal that indicates the cable connection state;
• and
• modifying an impedance transform of a tunable matching circuit in response to the cable detection signal indicating a presence of the cable connector, wherein the tunable matching circuit couples the modified impedance transform between a transceiver and an antenna.
