Abstract
A system can obtain an operational metric associated with the transceiver, determine a target figure of merit based on a compromise between a desired transmitter performance and a desired receiver, determine a current figure of merit based on the operational metric, and adjust the variable reactance component of the impedance matching circuit based on a comparison of the current figure of merit with the target figure of merit. Other embodiments are disclosed.
