Classification: CPC H | IPC H

Claim 1:
2. The phase-variable frequency multiplier according to claim 1, wherein
the amplitude setting circuit includes:
a first variable gain amplifier to set an amplitude of the first in-phase signal of the two distributed in-phase signals so that the amplitude of the first in-phase signal is a cosine of the phase shift amount; and
a second variable gain amplifier to set an amplitude of the second quadrature signal of the two distributed quadrature signals so that the amplitude of the second quadrature signal is a sine of the phase shift amount,
the first mixer multiplies the first in-phase signal with the amplitude set by the first variable gain amplifier by the first quadrature signal of the two quadrature signals distributed by the amplitude setting circuit to generate the first signal, and
the second mixer multiplies the second in-phase signal of the in-phase signals distributed by the amplitude setting circuit by the second quadrature signal with the amplitude set by the second variable gain amplifier to generate the second signal.
