ABSTRACT:
A diode mixer comprises a mixer diode section which has a first circuit including an inductor and a capacitor connected in series and a diode connected in parallel with the first circuit and which includes a first connecting portion to which one end of the first circuit and the anode of the diode are connected, and a second connecting portion to which the other end of the first inductor circuit and the cathode of the diode are connected; an LO signal port connected to the first connecting portion via a first branching circuit and receiving an LO signal; an IF signal port connected to the mixer diode section via a second branching circuit; and an RF signal port connected to the mixer diode section through a third branching circuit. The inductor and the capacitive component of the diode constitute a resonant circuit.
