Patent ID: 7973615

Claim:
An RF module comprising: a waveguide in which a half-wavelength TE mode resonator is formed, the TE mode resonator having an H plane; a plurality of wall portions constructing the waveguide to form the TE mode resonator, and two H plane coupling windows formed in one of the plurality of wall portions parallel with the H plane of the TE mode resonator; a first output line provided at a center side edge of the TE mode resonator in one of the two H plane coupling windows, and the first output line is magnetically coupled to TE mode electromagnetic waves in the TE mode resonator; and a second output line provided at an outer periphery side edge of the TE mode resonator at an edge of the other of the two H plane coupling windows and the second output line is magnetically coupled to the TE mode electromagnetic waves, the first output line and the second output line being respectively short-circuited to the corresponding wall portion in which the two H plane coupling windows are formed, and a balanced signal being output to the first output line and the second output line.
