Keysight / Agilent 8474 Series Planar-Doped Barrier Diode Detectors

  • Exceptional Flatness
  • Broadband from 0.01 to 50 GHz
  • Extremely Temperature Stable
  • Environmentally Rugged


The Keysight / Agilent 8474 Series Planar-Doped Barrier Diode Detectors are specifically designed for use in microwave instrumentation and systems. These detectors utilize a GaAs diode matched to a 50 Ω transmission line with a miniature thin film circuit.

The diodes are a Planar-Doped Barrier (PDB) structure fabricated by use of Molecular Beam Epitaxy technology. This combination yields a device which has superior characteristics to point-contact and low-barrier Schottky devices. These characteristics are reflected in frequency response specification and in square law response vs. frequency with PDB detectors showing a maximum square law response variation of 3% from 2 to 18 GHz vs. 9.5% for Schottky detectors.

These detectors are extremely rugged with high resistance to ESD damage and are less sensitive to temperature change than either point-contact or Schottky diodes. These products offer 10 MHz to 50 GHz performance with the 2.4 mm connector (8474E) or narrower frequency coverage with APC-7 Type N or SMAcompatible 3.5 mm and 2.92 mm connectors. There is no need to order matched pairs because the frequency tracking is better than the original matched pair specifications.

Product Family: 8474 Series, 8474, 8474B, 8474C, 8474E

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!

InstraView Request Form

To get started:

  1.   Fill in the request form below
  2.   We'll send you an email letting you know exactly when your piece of equipment will be available for viewing
