DC132: Directional Coupler for R22 Waveguide
DC132 is a small-housing directional coupler intended for sampling incident or reflected waves in high-power 2450 MHz industrial applications using an R22 (WR430) 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.
