摘要

A radio frequency switching device includes: a first series switching circuit connected between a first terminal and a second terminal; a first shunt switching circuit connected between one end of the first series switching circuit and a ground; a voltage generation circuit configured to generate a first gate voltage to be output to the first series switching circuit, to generate a second gate voltage to be output to the first shunt switching circuit, and to generate a bias voltage higher than the second gate voltage to control the first shunt switching circuit to enter an off state; a first resistance circuit connected between a signal line between the first terminal and the second terminal, and a bias voltage terminal of the voltage generation circuit; and a second resistance circuit connected between the bias voltage terminal of the voltage generation circuit and a ground terminal of the first shunt switching circuit.
