Provided are a transfer gate circuit that has reduced disturbance in an output waveform thereof, a power combining circuit using the transfer gate circuit, and a transmission device and a communication device that use the power combining circuit. The transfer gate circuit includes: output terminals (3, 4) ; a transistor (5) including a drain connected to the output terminal (3); a transistor (6) including a drain connected to the output terminal (4); transistors (7, 8) each including a drain connected to the output terminal (3) and each including a source connected to a ground potential; and transistors (9, 10) each including a drain connected to the output terminal (4) and each including a source connected to the ground potential. In the transfer gate circuit, the transistors (5, 6) include sources to which first and second input signals are input, respectively, the transistor (5) includes a gate to which a signal in phase with the second input signal is input, the transistor (6) includes a gate to which a signal in phase with the first input signal is input, the transistors (7, 9) each include a gate to which a signal in antiphase to the second input signal is input, and the transistors (8, 10) each include a gate to which a signal in antiphase to the first input signal is input. |
