Non-contacting waveguide T switch

摘要

A non-contacting waveguide "T" switch (10) is provided including a stator (12), a rotor (14) mounted for rotation relative to the stator, and a coaxial conductor (64) located at the axis of the rotor for carrying a coaxial transmission. The stator (12) has at least one waveguide port (32). The rotor (14) includes a through-waveguide (48) and an impedance matching transformer (52) disposed in the through-waveguide (48) for converting the coaxial transmission into a waveguide transmission. The transformer (52) has a bore which forms a non-contacting sleeve about the coaxial conductor (64). The through-waveguide (48) carries the waveguide transmission radiated from the transformer to the at least one waveguide port (32).
