Description

HP Hewlett Packard H424A Crystal Detector WR-112 Waveguide BNC 7.05-10.0 GHz X-Band

A waveguide-mounted crystal detector for X-Band microwave applications. This detector converts RF signals to measurable DC output via a semiconductor crystal element, used for signal detection and measurement in radar and communication systems.

Specifications & What's Included

  • Model: H424A
  • Frequency Range: 7.05 to 10.0 GHz (X-Band)
  • Waveguide: WR-112 Standard Flange
  • Output Connector: BNC
  • Detector Polarity: Negative
  • Manufacturer: Hewlett-Packard, USA
  • Includes blue protective flange cover

Applications

Crystal detectors like the H424A were used in radar systems, test equipment, and microwave communication platforms for signal detection and power measurement. The WR-112 waveguide and X-Band frequency range make this compatible with legacy and industrial RF measurement setups from the 1970s through 1990s.

Condition: Used
This Hewlett Packard H424A Crystal Detector has been inspected and is in good used condition. It was pulled from a working environment where it was in active use. The body shows typical surface wear consistent with bench or lab use, and the WR-112 waveguide flange face shows light scuffing and minor marks visible in the photos. The BNC output connector is clean and intact. The blue protective plastic flange mount/cover is present. The label is fully legible, confirming model H424A (NEG).
