BD132B: Bidirectional Detector for R22 Waveguide, with DC Amplifiers
BD132B is a bidirectional detector intended for simultaneous sampling of incident and reflected waves in high-power 2450 MHz industrial applications using an R22 (WR430) rectangular waveguide. The bidirectional detector combines the following components:
- Dual directional coupler
- Zero-bias Schottky diode detectors
- Low noise operational amplifiers
The unit delivers two DC voltages in the range 0 to approximately 9 V. The voltages are functions of the powers associated with waves propagating in opposite directions in the parent waveguide. Standard maximum working powers Pmax are 1 kW, 10 kW, and 30 kW.
