Summary:A voltage detecting apparatus includes a signal extracting circuit configured to extract a coupled signal from a signal output by a power amplifier configured to amplify a signal output by a radio frequency (RF) circuit, and a voltage detecting circuit configured to detect a detection voltage from the coupled signal and provide the detection voltage to the RF circuit. The voltage detecting circuit configured to vary the detection voltage in response to an input control signal.
