SUMMARY

This discussion focuses on sourcing microwave diodes, specifically Schottky diodes for high-frequency rectification. The user highlights a preference for GaAs Schottky diodes, which can achieve cutoff frequencies exceeding 800 GHz, as referenced in Sze's textbook. Manufacturers mentioned include Agilent, now part of Avago Technologies, and Virginia Diodes, which offers products suitable for millimeter wave applications up to several THz. The conversation emphasizes the specialized nature of these components, including their high cost and the need for precise bonding techniques.

PREREQUISITES
  • Understanding of Schottky diodes and their applications in microwave technology.
  • Familiarity with GaAs semiconductor properties and advantages over silicon.
  • Knowledge of millimeter wave technology and its frequency ranges.
  • Experience with diode bonding techniques and equipment, including microscopes.
NEXT STEPS
  • Research GaAs Schottky diode specifications and manufacturers.
  • Explore the capabilities of Virginia Diodes for millimeter wave applications.
  • Investigate bonding techniques for high-frequency diodes.
  • Learn about the performance characteristics of microwave diodes at various frequencies.
USEFUL FOR

Engineers and researchers in the fields of microwave technology, RF design, and semiconductor manufacturing, particularly those seeking high-frequency rectification solutions.

Does anybody know any good manufacturers of microwave diodes?

Specifically, I'm looking for rectification that can be operated at essentially as high of a frequency as I can get. This led me to look for Schottky diodes (anybody have a better suggestion?).

So far, all the microwave Schottky diodes I have found use silicon and have a 40 GHz cutoff. However, Sze has a plot (Fig. 37, Ch. 3, 3rd Ed.) that shows GaAs Schottky diodes with cutoff frequencies upwards for 800 GHz! Hell, anybody know where I can get these bad boys? :confused:
 
Engineering news on Phys.org
Beam lead diodes are popular in millimeter wavelengths, work up to 300 GHz.

One of the manufacturers was Agilent, but they recently sold off their semiconductor division to Avago

some of these diode are like $50 bucks a piece and require special bonding and a microscope to attach them to a substrate, or a waveguide.

Another place for millimeter waves:

they have cool gizmos up to a couple THz.
 
Cool stuf; thanks, waht!
