Abstract
An improved switching arrangement 10 for waveguide is disclosed which comprises, in combination, a coaxial switch 12 and a unified, multi-port, waveguide interface 14. The coaxial switch 12 has coaxial connectors of a first type (12a, 12b, 12c) mounted in a parallel pattern with a preestablished center-to-center spacing. The waveguide interface 14 includes flanges (14a, 14b, 14c), and is preferably formed as a waveguide housing having a transition plate portion and a cover plate portion. Each port of the unified waveguide interface includes internal waveguide-to-coax transitions for coupling to a respective external connector of a second type. The external coaxial connectors (16a, 16b, 16c) are configured in a parallel pattern with center-to-center spacings equal to the preestablished center-to-center spacings of the coaxial switch connectors (12a, 12b, 12c) such that these connectors mate directly with those of the unified waveguide interface. By so doing, intervening coaxial cables or adaptors are eliminated and relatively low insertion loss and fast switching speed are exhibited over a relatively broad bandwidth.
