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
- 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.
