Directional Couplers Multi-Hole
PENN ENGINEERING's Directional Couplers are an excellent method for measuring the microwave energy traveling through a waveguide system.

  • Coupling values of 3, 6, 10, and 20 dB are available with nominal coupling values of +/- .4dB.
  • Coupling values of 30 and 40 dB are available with nominal coupling value of +/- 1.0 dB.
  • On models in WR-28, WR-34, WR-42, and WR-51: The coupling values are +/- .6 dB and +/- 1.2 dB.

Custom coupling values are available on request.

Main line VSWR is 1.05:1 maximum (1.10:1 for the 3 dB coupling). Broad band directivity is greater than 40 dB (except for the WR-28, WR-42, and WR-51 which is 35 dB.)

Brass units are Silver plated per QQ-S-365D Class A, Aluminum units are Chem-filmed per MIL-C-5541E, and both are finished with PENN ENGINEERING's Metallic Blue Paint.
