Abstract
A radio frequency switch includes a control buffer circuit to generate a first gate voltage and a first body voltage; and a switching circuit to switch at least one signal path in response to the first gate voltage and the first body voltage. The control buffer circuit includes an off voltage detection circuit to detect whether the off voltage is a negative voltage or a ground voltage and output a voltage detection signal, a first gate buffer circuit to output a first gate voltage having a voltage level based on the voltage detection signal and the band selection signal, and a first body buffer circuit to output a first body voltage having a voltage level based on the voltage detection signal, the band selection signal, and the mode signal.
