DD132: Directional Detector for R22 Waveguide

DD132 is a small-housing directional detector intended for sampling incident or reflected waves in high-power 2450 MHz industrial applications using R22 (WR430) rectangular waveguide.

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

Simple reversing the DD132 causes it to sample the wave propagating in the opposite direction.
