Welcome to my High Frequency Measurements Web page. Below you will find links to interesting technical goodies for download, as well as other interesting websites, information on my seminars, and much more. I will be adding to this site weekly, so check back occasionally. Feel free to print out pages on this site and to give them to others, but I ask you to include the complete page with header. Check out the monthly Technical Tidbit article linked at the bottom of this page. Each one will illustrate a design or measurement principle, sometimes what not to do. HF News is back! If you want to subscribe just send me an email at doug@dsmith.org with "HFNews" as the subject line. There is a link in each issue to unsubscribe if you want to, but you won't! Each issue contains useful technical discussion and links to explore and is short and to the point, like my Technical Tidbits below, so as not waste your time. Each issue can be read in two or three minutes. Your email address will be kept private and never be given or sold to anyone.Here is a link to the January 30, 2017 issue: ESD Issues . Subsequent issues will be archived further down this page.

You may also enjoy my Twitter feed. Just go to http://twitter.com and follow me at @dougcsmith_ee . I usually post short items such as interesting technical links once or twice per day.

Design and Troubleshooting Tips and Techniques: You will find many tips on design and troubleshooting on this site, yet what you see is just the "tip of the iceberg" compared to what is available in my on-site private seminars. The seminars cover many effective design and troubleshooting techniques developed by myself and not taught anywhere else! Click here to request more information via email.
