DC123: Directional Coupler for R32 Waveguide

DC123 is a small-housing directional coupler intended for sampling incident or reflected waves in high-power 2450 MHz industrial applications using an R32 (WR284) rectangular waveguide.

The coupler is fixed to the waveguide with six M3 or similar-diameter screws after machining of appropriate holes in the broad waveguide wall.

Simply reversing the coupler causes it to sample the wave propagating in the opposite direction.
