Orthomode transducer between a circular waveguide and a coaxial cable.

摘要

The orthomode transducer between a circular waveguide and a coaxial cable consists of a circular waveguide section, into which two probes externally connected to coaxial connectors penetrate. The probe placed close to the input aperture of the waveguide is tuned by a screw and a metal plate belonging to the same axial plane and the other probe is tuned by a screw and a circular disc which closes the waveguide. The shapes of the plate and of the probes are such as to allow the best power coupling between the optical guide and the coaxial line over a wide operating band (10% of the mid-band frequency). <IMAGE>
