COAXIALLY CONFIGURED OMT-MULTIPLEXER ASSEMBLY

摘要

An ortho mode transducer (OMT)/multiplexer assembly (20) having a corrugated junction (41) and a coaxial dual mode waveguide resonator (53) disposed around a central cylindrical waveguide (23). The corrugated junctio n (41) diplexes signals, the higher frequencies passing through the central cylindrical waveguide (23) and the lower frequencies passing through the coaxial dual mode resonator (53). Apertures (62) in the dual mode resonator (53) couple to an exit port (86) and extract a first polarization from the lower frequencies passing through the dual mode resonator (53). The assembly may include a second aperture (65) in the dual mode resonator (53) for extractin g a second polarization in a manner similar to the operation of the first apertu re (62).
