Non-contacting waveguide "T" switch

A waveguide switch comprising:

• a stator having at least one waveguide port;
• a coaxial conductor comprising a center conductor and a outer conductor for carrying a coaxial transmission, the coaxial conductor being affixed to the stator;
• and
• a rotor mounted for rotation relative to the stator, the rotor including a first waveguide and a single impedance matching transformer disposed in the waveguide for receiving said coaxial center conductor and converting the coaxial transmission into a waveguide transmission, the transformer having a bore which forms a non-contacting sleeve about the coaxial conductor, the first waveguide carrying the waveguide transmission radiated from the transformer to the at least one waveguide port.

A waveguide switch comprising:

• a stator having at least two waveguide ports;
• a first impedance matching transformer disposed within one of the at least two waveguide ports for converting a waveguide transmission into a coaxial transmission;
• a coaxial conductor having a center conductor and a outer conductor, the outer conductor having a first end affixed to the first impedance matching transformer and a free end, the center conductor carrying the coaxial transmission;
• and
• a rotor mounted for rotation relative to the stator, the rotor including a first waveguide and a second impedance matching transformer disposed in the first waveguide for converting the coaxial transmission into a waveguide transmission, the second impedance matching transformer having a bore which forms a non-contacting sleeve about the free end of the center conductor, the first waveguide carrying the waveguide transmission radiated from the second impedance matching transformer to the other of the at least two waveguide ports.
