Abstract:
1. A method for termination impedance selection in a power amplifier module, the method comprising: generating a first radio frequency signal using a first power amplifier of the power amplifier module; generating a second radio frequency signal using a second power amplifier of the power amplifier module; determining at least one of a power mode or a frequency band of operation of the power amplifier module, the power amplifier module including a multi-band directional coupler including a first signal pathway associated with the first radio frequency signal and a second signal pathway associated with the second radio frequency signal; and selecting a termination impedance of the multi-band directional coupler based on the determination using at least one switch, the at least one switch including a first switch electrically connected in series with a first capacitor and a second capacitor between a terminate terminal of the multi-band directional coupler and a reference voltage.
