Abstract
Provided is an even harmonic mixer which is reduced in cost and size. The even harmonic mixer includes: a transducer in which a conductor of a microstrip line is connected to a ground plane of a waveguide, for transducing an RF signal transmitted in a waveguide mode into a transmission mode of the microstrip line; an anti-parallel diode pair which is cascade-connected to a microstrip line side of the transducer, and formed on a semiconductor substrate; a branching circuit for branching an LO signal and an IF signal; an open-end stub which is disposed between the transducer and the anti-parallel diode pair, and has a line length of about ½ wavelength at an RF signal frequency; and an open-end stub which is disposed between the anti-parallel diode pair and the branching circuit, and has a line length of about ¼ wavelength at the RF signal frequency.
