DD141: Fast Temperature-Stable Directional Detector for Coaxial Waveguide 23/47 mm

DD141 is a directional detector intended for sampling pulse-modulated incident or reflected waves in high-power 2450 MHz industrial applications using coaxial waveguide 23/47 mm.

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 DD141 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.
