BC111: Bidirectional Coupler for WR340 Waveguide

BC111 is a bidirectional coupler intended for simultaneous sampling of both incident and reflected waves in high-power 2450 MHz industrial applications using an WR340 (R26) rectangular waveguide.

Nominal coupling factor is -60 dB for maximal input power 10 kW in the waveguide.

The coupler is fixed to the parent waveguide using eight M3 or similar-diameter screws after machining of appropriate holes in the broad waveguide wall. The parent waveguide (standard or customized) can optionally be part of delivery. The standard length is 174 mm.
