Abstract
Various embodiments may provide a circuit including a radio frequency (RF) power amplification module having an RF power amplifier. The RF power amplification module may further include a directional coupler coupled with the RF power amplifier and configured to produce a power signal at a coupling port of the directional coupler corresponding to an output power of the RF power amplifier. The RF power amplification module may further include a switch coupled between the coupling terminal and a sensing path to selectively couple the coupling port with a power detector via the sensing path. The RF power amplification module may further include a termination load coupled to an isolation port of the directional coupler. Some embodiments may include a plurality of RF power amplification modules coupled together by the sensing path.
