DC211: Directional Coupler for R9 Waveguide
DC211 is a directional coupler intended for sampling incident or reflected waves in highpower 900 MHz industrial applications using R9 rectangular waveguide.
The coupler is fixed to the waveguide with eight M3 or similar-diameter screws after machining of appropriate holes in the broad waveguide wall.
Simple reversing the coupler causes it to sample the wave propagating in the opposite direction.
