83036C Broadband Directional Detector, 10 MHz to 26.5 GHz

The Keysight 83036C Broadband Directional Detector is a high-performance microwave power sampler that integrates directional coupling and detection into a single compact element. Operating from 10 MHz to 26.5 GHz, it eliminates the need for separate directional coupler and detector combinations while maintaining superior frequency response characteristics.
