BD214: Bidirectional Detector for R9 Waveguide

BD214 is a bidirectional detector intended for simultaneous sampling of incident and reflected waves in high-power 900 MHz industrial applications using an R9 (WR975) rectangular waveguide. The bidirectional detector combines the following components:

  • 4-port directional coupler
  • Attenuators
  • Zero-bias Schottky diode detectors

The detector delivers two well-scaled DC voltages proportional to power of the waves propagating in forward and reverse directions in the parent waveguide. Standard maximum working powers Pmax are 10 kW and 100 kW.
