Planar-Doped Barrier Diode Detector, 0.01 to 50 GHz
8474E
The Keysight 8474E is a high-performance detector using a gallium arsenide, planar-doped barrier detecting element. It features extremely flat frequency response over its entire band of operation and very good frequency response stability versus temperature. The Keysight 8474E is also very rugged with high resistance to ESD damage. The Keysight 8474E detector is available with a 2.4-mm (0.01 to 50 GHz) connector. This detector offers the options for optimal square-law loads (Option 102) and for positive polarity output (Option 103). Because the unit-to-unit frequency response tracking of this device is typically better than plus or minus 0.3 dB, no matched response option is offered.
