DD122 is a miniature directional detector intended for sampling incident or reflected waves in high-power 2450 MHz industrial applications using R-32 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 DD122 causes it to sample the wave propagating in the opposite direction.
