Abstract
A radio frequency (RF) switch circuit that outputs signals input through first and second input ports to an output port is provided. The RF switch circuit includes a first series switch that outputs the signal input through the first input port; a first shunt switch connected to the first input port; a first attenuation circuit connected between the first shunt switch and ground and attenuating the signal output from the first input port to the output port; a detector that detects a magnitude of a signal output to the output port and generates a first control signal based on the magnitude of the detected signal; and a switch control circuit that controls the first series switch, the first shunt switch, and the first attenuation circuit with the first control signal and a second control signal to select a signal path between the first input port and the output port.
