Patent ID: 7330087

Claim:
A microwave switch housing assembly for operation in a selected frequency range, comprising: (a) a housing; (b) a rotor rotatably mounted within said housing; (c) at least one waveguide passage in said rotor; (d) said housing having ports formed therein so that in a first position of said rotor, said waveguide passage connects said ports and in a second position of said rotor, said waveguide passage is unconnected to said ports; (e) a channel formed within one of said housing and said rotor such that said channel is positioned adjacent to one end of said waveguide passage when said rotor is in said second position; (f) a said power absorbing element positioned and secured within said channel, a side of said power absorbing element being aligned with one of the inner radius of the housing and the outer radius of the rotor being capable of absorbing electromagnetic energy in said frequency range, so as to reduce the tendency of said waveguide passage to act as a volume resonator when said rotor is in said second position.
