ABSTRACT:
A diplexer (14) has a first rectangular waveguide (38) extending from a front port (16) to a back wall (70), the back wall having a rectangular opening (72) therein constituting a section of a second rectangular waveguide (20) and serving as a back port (18) of the diplexer. A first spectral region of electromagnetic power communicates between the front port and a side port (28), and a second spectral region of electromagnetic power communicates between the front port and the back port. A center frequency of the second spectral region is greater than a center frequency of the first spectral region by a factor greater than or equal approximately to two. The side port includes an aperture (126) disposed in a sidewall (42) of the first waveguide, a third waveguide (32), and a coupling element (128) extending from the third waveguide through the aperture into the first waveguide for coupling electromagnetic power at the first spectral region between the first and the third waveguides. Coupled resonators (112, 124) disposed within the third waveguide provide a bandpass filter characteristic at the first spectral region, and inhibit propagation of electromagnetic power at the second spectral region between the first and the second waveguides. Within the inner conductor are two spaced apart cylindrical elements (100, 112) constituting plates of a capacitor (102).
