The present disclosure discloses a radio frequency switching circuit including an antenna terminal, a transmitter terminal, a receiver terminal, a first switching module, a second switching module, a first switching component, and a second switching component. The first switching module is connected between the antenna terminal and the transmitter terminal. The second switching module is connected between the antenna terminal and the receiver terminal. The first and second switching modules include several transistors respectively, and each of the transistors includes a gate terminal, a drain terminal, a source terminal, and a bulk. The first switching component has a first anode terminal connecting with the gate terminal, and a first cathode terminal connecting with the drain terminal. The second switching component has a second anode terminal connecting with the gate terminal, and a second cathode terminal connecting with the source terminal.
