Abstract
A radio-frequency switching circuit includes a first switching circuit connected between a common capacitor connected to an antenna port and a first capacitor connected to a first port, and performing a switching operation with a first gate voltage transmitted through a first gate terminal, a voltage generation circuit supplying a drain-source voltage to a common node disposed at a first end of the first switching circuit, and a voltage detection circuit receiving a node voltage from the common node, comparing the node voltage with a reference voltage, and generating a detection voltage including damage information regarding the common capacitor or the first capacitor.
