器。 A local oscillator, an attenuator connected to its output, a diode that mixes the local oscillator signal from the attenuator with an RF signal from a separately provided microwave input terminal, and a bias circuit that applies a DC bias to the diode. A frequency mixer, characterized in that the attenuator stabilizes the operation of the local oscillator, and the level drop caused by the attenuator is compensated for by applying a bias to the diode.
