Abstract
Methods for directional coupler termination impedance control are provided. In one embodiment, a method for termination impedance selection of a directional coupler in a power amplifier module is provided. The method includes determining at least one of a power mode or a frequency band of operation of the power amplifier module. The method further includes selecting a termination impedance of the directional coupler based on the determination using at least one switch.
