Waveguide High Power Termination

ARRA Inc. manufactures a full line of high power waveguide terminations. Arra’s high power waveguide termination models are available in a host of waveguide flanges: WR28, WR42, WR62, 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.

GENERAL SPECIFICATIONS
  • VSWR:1.15 max
  • Material:Aluminum
  • Flange Type:Cover Standard
  • Finish:High temperature black paint

OPTIONS

1. For brass material, add B to basic model number.
2. For choke flange, precede model number with C.
3. For CPR or other flange, precede model number with
flange type. Ex: CPR137G-920.
4. Shorter lengths and different power capabilities
available on request; contact factory.
