Claim 3:
4. The transmission device according to claim 1, further comprising:
a third mixer configured to mix a second input signal with the intermediate frequency and the local signal amplified by the first amplifier, the second input signal having a phase different from the first input signal by 90 degrees, and to output a third output signal;
a fourth mixer configured to mix the third output signal output from the third mixer and the local signal amplified by the first amplifier and to output a fourth output signal;
a phase shifter configured to adjust a phase of the fourth output signal to match phases of the second output signal and the fourth output signal; and
an adder configured to add the second output signal and the fourth output signal of which the phases are matched.
