Abstract
A transducer and a mixer with a double-balanced output according to the current invention are capable of frequency conversion in a microwave band with low distortion. The transducer or the mixer has symmetry of wirings. One side of a printed circuit board has branched strip lines and a single strip line whose base portion serves as an RF input terminal, and the other side of the printed circuit board has twin-branched ground strips and a bridge-shaped ground strip. The combination of the branched strip lines and the twin-branches strips, and the combination of the single strip line and the bridge-shaped ground strip serve as a transducer. One pair of diagonal terminals of the symmetrical diode ring is connected to the base portion of the branched strip lines. The other pair of diagonal terminals is connected to the tip of the single strip line. The diode ring is connected to a transducer. One winding thereof is supplied with a local oscillator. An IF terminal is coupled to the center of the other winding thereof.
