DD113 is a miniature directional detector intended for sampling pulse-modulated incident or reflected waves in high-power 2450 MHz industrial applications using R-26 rectangular waveguide.
The detector delivers well-scaled DC voltage proportional to the power of the wave propagating in one direction in the main waveguide. Output voltage can be scaled according to customer's demands.
Simple reversing the DD113 causes it to sample the wave propagating in the opposite direction.
The tunnel diode detector module assures high temperature stability of the output voltage and low video resistance for fast pulse rise/fall times.
