<p>This invention provides an quadrature mixer which does not require a long time to adjust the amplitude value at the time of demodulation of the IQ signal. The quadrature mixer, comprising a first frequency-conversion unit that outputs a sixth signal derived by multiplying a first signal by a second and a fourth signals, a second frequency-conversion unit that outputs a seventh signal derived by multiplying the first signal by a third and a fifth signals, a first amplitude adjustment unit that outputs a eighth signal derived by multiplying the sixth signal by the third and fifth signals and a second amplitude adjustment unit that outputs a ninth signal derived by multiplying the seventh signal by the second and fifth signals.</p> |
