Waveguide Medium Power Termination

ARRA Inc. manufactures a full line of medium power waveguide terminations. Arra’s medium power waveguide termination models are available in a host of waveguide flanges: WR28, WR42, WR51, WR52, WR75, WR90, WR102, WR112, WR137, WR159, WR187, WR229, WR284. Offering low loss, low VSWR; we designed our low power waveguide terminations to absorb power with high isolation thus terminating the source power from a waveguide, leaving little to no reflection.
