QEX May 2023: Diode Characterization

One of Chelsea’s very own, Wesley Cardone (N8QM), has been published by the ARRL May 2023 QEX journal.

The American Radio Relay League (ARRL) QEX journal of May 2023 has featured its lead article from a draft submitted by Chelsea’s own

You can view the original draft that Wes sent to the ARRL in January of 2022.

Wes gave a presentation on the paper at the 2023 Chelsea Amateur Radio Hamfest Swapmeet. Click here to see the PDF presentation document.

About Wes

Please visit www.QRZ.com and lookup N8QM.

Wes is considered an industry expert regarding conserved analog conservation and has extensive knowledge and many years of experience to that end. This includes:

  • Macro Modeling
  • Model characterization
  • Model development and
  • An acute understanding of what is under the hood with the SPICE and conserved simulation engines.

While the article was written within the reference of LTSpice, the fundamental model lying within the LTSpice diode is an industrial standard. The characterization is therefore applicable to SPICE knock-off engines such as Orcad, Altium, and PSpice. At the same time, the characterization is directly applicable to industrial conserved engines including the Ansys Simplorer, Synopsys Saber, and Siemens AIMSim tools.

Mr. Cardone will be giving a presentation about the article at the 2023 Chelsea Amateur Radio Hamfest-Swap Meet on June 4th.
