DC141 is a directional coupler intended for sampling incident or reflected waves in high-power 2450 MHz industrial applications using 23/47 mm coaxial waveguide.
The coupler is fixed to the waveguide with six M3 or similar-diameter screws after machining of appropriate holes in the special waveguide part with platform.
Simple reversing the coupler causes it to sample the wave propagating in the opposite direction.
