Abstract
Acoustic impedance tuning in a wireless transmission circuit (a.k.a. wireless device) is provided. In aspects discussed herein, the wireless transmission circuit includes an acoustic load-line tuning circuit that can be configured to adapt a load-line impedance presenting to a power amplifier circuit. In embodiments disclosed herein, the acoustic load-line tuning circuit can be dynamically controlled to provide impedance matching between a power amplifier circuit and other load-line circuits (e.g., filter circuits, antenna switch circuits, and/or antenna circuits). As a result, it is possible to reduce a signal reflection resulting from an impedance mismatch between the power amplifier circuit and the load-line circuits, thus helping to improve performance of the wireless transmission circuit.
