BD112B: Bidirectional Detector for R26 Waveguide, with DC Amplifers
BD112B 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:
- 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. The standard options for maximum working power are 1 kW, 3 kW, 10 kW, and 30 kW. In addition to these, customized maximum powers are optionally available.
