RF module

An RF module comprising:

• a waveguide in which a half-wavelength TE mode resonator is formed;
• at least one H plane coupling window formed in a wall portion parallel with an H plane out of wall portions constructing the TE mode resonator in the waveguide;
• one output line provided at either the edge on the center side or the edge on the outer periphery side of the TE mode resonator in the one H plane coupling window, and magnetically coupled to electromagnetic waves in the TE mode resonator;
• and
• another output line provided at either the edge on the center side or the edge on the outer periphery side of the TE mode resonator at the edge of either the one H plane coupling window or another H plane coupling window and magnetically coupled to the electromagnetic waves,
• the one output line and the another output line being respectively short-circuited to the wall portion in which the at least one H plane coupling window is formed, and
• a balanced signal being output to the one output line and the other output line, wherein
• two H plane coupling windows formed in two wall portions parallel with an H plane in wall portions constructing the TE mode resonator are provided as the H plane coupling window,
• the one output line is provided at either the edge on the center side or the edge on the side of the outer periphery of the TE mode resonator in one of the two H plane coupling windows, and magnetically coupled to electromagnetic waves in the TE mode resonator, and
• the another output line is provided at the edge in the other of the two H plane coupling windows, which is the edge on the same side as the edge at which the one output line is provided in one of the H plane coupling windows, and magnetically coupled to the electromagnetic waves.
