Abstract

A tunable matching network is configured to couple at least one filter with a power amplifier that is configured to operate in an envelope tracking (ET) mode of operation over a transmit band. A control component is configured to detect a present set of operating conditions of the power amplifier when the power amplifier operates in the ET mode of operation. The present set of operating conditions comprises a present frequency of operation, and the control component is further configured to transmit a control signal to the tunable matching network in response to the detected present set of operating conditions. The tunable matching network is further configured to adjust an impedance of the tunable matching network in response to the transmitted control signal such that one or more ET characteristics are optimized based at least in part on the present set of operating conditions.
