BD112: Bidirectional Detector for R26 Waveguide

BD112 is a bidirectional detector intended for simultaneous sampling of incident and reflected waves in high-power 2450 MHz industrial applications using an R26 (WR340) rectangular waveguide. The bidirectional detector combines the following components:

  • 4-port directional coupler (70-dB coupling)
  • Attenuators
  • Zero-bias Schottky diode detectors

The detector delivers well-scaled DC voltages proportional to power of the waves propagating in forward and reverse directions in the main waveguide. Standard maximum working powers Pmax are 1 kW, 10 kW and 30 kW.
