Abstract

A novel millimeter-wave 3-dB power combining circuit fabricated using millimeter wave microstrip integrated technique has been developed. This combing circuit consists of a new style 3-dB combiner, which achieves low-loss, wide-band, and symmetric power division. Different from common Wilkinson hybrid in structure, the proposed combiner requires no isolating resistor, and is easier fabricated and suitable for millimeter wave integrated circuits. The developed 3-dB power combining circuit exhibited a record high power-combining efficiency of 85% in 33.2GHz∼34.0GHz.
