Abstract
Disclosed is a harmonic mixer including N transistors, an RF terminal, N LO terminals, an IF terminal, a series resonant circuit, and an IF matching circuit, in which when the RF frequency of a high frequency signal is identical or close to the maximum oscillation frequency of the transistors, the impedance seen from the IF terminal toward an output terminal at the RF frequency becomes low, and the impedance seen from the IF terminal toward the output terminal at an IF frequency is the combination of the impedance of the series resonant circuit and the impedance of the IF matching circuit.
