Classification: CPC H | IPC H

Claim 17:
18. The electronic device according to claim 17,
wherein the data output device outputs the first input signal and a second input signal with the intermediate frequency, the second input signal having a phase different from the first input signal by 90 degrees, and
wherein the transmission device further includes
a third mixer configured to mix the second input signal and the local signal amplified by the first amplifier, 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.
