DD112: Directional Detector for R26 Waveguide

DD112 is a small-housing directional detector intended for sampling incident or reflected waves in high-power 2450 MHz industrial applications using an R26 (WR340) rectangular waveguide.

The detector delivers well-scaled DC voltage proportional to the power of the wave propagating in one direction in the main waveguide.

Simply reversing the DD112 causes it to sample the wave propagating in the opposite direction.
