Waveguide Low Power Termination

ARRA Inc. manufactures a full line of low power waveguide terminations. Arra’s low power waveguide termination models are available in a host of waveguide flanges: WR28, WR34, WR42, WR51, WR62, WR75, WR90, WR102, WR112, WR137, WR159, WR187, WR229, WR284, WR340, WR430, WR650. 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.
