ORTHOGONAL MIXER

摘要

Disclosed is an orthogonal mixer which does not require a long time to adjust the amplitude value when demodulating an IQ signal. The orthogonal mixer is characterised by the inclusion of: a first frequency-changing unit (12), which outputs a sixth signal (MIXC_I), derived by inputting and multiplying a first signal (IN) with a second signal (CLKI) and a fourth signal (CLKIB); a second frequency-changing unit (13), which outputs a seventh signal (MIXC_Q), derived by inputting and multiplying the first signal with a third signal (CLKQ) and a fifth signal (CLKQB); a first amplitude adjustment unit (14), which inputs the sixth signal and the third signal and fifth signal and outputs an eighth signal (MIX_I); and a second amplitude adjustment unit (15), which inputs the seventh signal and the second signal and fourth signal and outputs a ninth signal (MIX_Q).
