HP 8474C 33 GHz Planar-Doped Barrier Diode Detector

Product Summary

The HP 8474C 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 HP 8474C is also very rugged with high resistance to ESD damage. An optimum square-law load and positive polarity output are available as special options.

Product Features

• Exceptional flatness

• Extremely temperature stable

• Rugged
