Patent ID: 7439829

Claim:
An RF module comprising: a waveguide in which a half-wavelength TE mode resonator having wall portions is formed; one or more E plane coupling windows formed in one or more of the wall portions orthogonal to an H plane; a first output planar line provided at a first edge of a first E plane coupling window of the one or more E plane coupling windows, the first output planar line being magnetically coupled to electromagnetic waves in the TE mode resonator and outputting electromagnetic waves in TEM mode, the first edge being parallel to the H plane; and a second output planar line being separately formed and electrically isolated from the first output planar line and provided at a second edge of the first E plane coupling window or a second E plane coupling window of the one or more E plane coupling windows that is different from the first E plane coupling window, the second output planar line being magnetically coupled to the electromagnetic waves and outputting electromagnetic waves in TEM mode, the second edge being parallel to the H plane.
