Abstract: A radio frequency (RF) front-end circuit has a multi-way switch, an output terminal, and a shunt circuit. The multi-way switch has an input end, a plurality of output ends, and a control end. The input end is coupled to an antenna for receiving a radio frequency signal from the antenna. The control end is used to couple the input end to one of the output ends according to a switch control signal. The shunt circuit is coupled between the multi-way switch and the output terminal to provide one of shunt paths according to the switch control signal. The shunt paths correspond to different amounts of rejection to the radio frequency signal.
