GaAs Schottky Diodes — W-Band Diodes In Stock

Our planar diodes are available as single devices or as multiple devices arranged in series, anti-series and anti-parallel configurations. These diodes provide state-of-the-art performance and reliability. Below is a pricing chart for our W-Band Diodes. Within the chart are links to the specifications for each part name. Notes above the table refer to specifications common to all four part names. VDI can provide 2-3 week delivery on diodes. Please call for additional information on other types of diodes.

VDI Notes on Diode Mount and Solder
The notes linked above are some general guidelines and details that may be helpful when flip-chip mounting/soldering VDI diodes to circuits. The procedure noted here is essentially the procedure used by VDI. The VDI diode solder contact pads are Au thin films. Process times and temperatures are variable and depend upon the Customer’s circuits or substrates being used. This outline is simply intended to give some general guidelines for diode flip-chip mounting and soldering.

VDI Notes on Diode Specifications (VDI-1004)
The notes linked above describe how to interpret VDI diode specifications.

To receive more information about VDI’s diodes and their applications, please contact VDI's technical support team at or Agilent ADS, AWR Corp. MWO (Microwave Office), and Agilent Genesys models for the W Band Single Anode and W Band ZBD diodes can be accessed at the Modelithics, Inc. website.

All diode orders ship with a specification sheet. Current/Voltage data for each die shipped can be included for a $300.00 surcharge which must be included as a separate line item on the purchase order. One surcharge applies to every order of 500 die or less; above 500 die there is an additional surcharge for every additional 500 die.

Diode Models

"MODELITHICS, INC. is a leading-edge technology company that provides comprehensive RF, microwave and mm-wave measurement services, and highly scalable, accurate, measurement-based models of electronic components for high frequency design. Modelithics models capture complex characteristics and parasitic effects of RF and MW components and designs. They offer scalable design parameters, such as substrate scaling, pad scaling and part value scaling, plus adjustable input parameters such as bias and temperature for active devices models. This provides for accurate matching to designers' applications. The models also work with optimization processes offered in certain EDA software. These features lead to increased first-pass design success and a more efficient design process.

Through the Modelithics Vendor Partner Program (MVP), Modelithics collaborates with RF component and semiconductor device manufacturers by developing top quality models for their products.
