As is always the case, we've been busy adding plenty of new stuff to Microwaves101. We ain't been slack, Cap'n Walker!



New for June 2021: Wilkommen im Sommer 2021, meine Freunden. Why are we attempting to speak in German?  Because the "live" International Microwave Symposium starts on June 7, and the English language called and told us they are tired of how it is being mangled and needed a rest. 

Nap time's over, what's new at Microwaves101?

  • IMS2021 is part live and part virtual.  Read about it here. Our booth number is 1544, across from Hyperlabs and next to West Bond. Hopefully we'll see you there on June 8 and 9.

  • We offer you a new page on semi-rigid coax.  We're not sure how we put in 20+ years on this web site without some focus on this industry workhorse. You'll find a summary table of different sizes, that include dimensions, cut-off frequency and exact impedances.

  • Our Where-are-they-now page has four new entries.  You don't want to miss our description of the end of MicroSemi.  Also, Applied Thin Films is now part of Vishay. Rachel sent us a link to comprehensive article on the history of Maxim Integrated. Thanks! Finally, Nuvotronics is now owned (through Cubic) by private investor, Veritas. 

  • We added "fraudit" to our portmanteau list, thanks to the anti-democracy party's "audit" of the 2020 presidentail election in Arizona.  Seriously, how did we get to a point where it is acceptable and even encouraged for adults to cheat to change an outcome they don't like?

  • Some of you may have noticed that we always feature a video of a music artist who has recently passed on, on the upper right of our front page. Call it a hobby, we don't usually draw attention to it, but this month's honoree is Lloyd Price AND June is African American Music month.  This celebration dates back to Jimmy Carter's proclamation that June 1979 would be Black Music Month. In 2009, Barack Obama updated the name. Want to learn more? Check out the Smithsonian National Museum of African American History & Culture's Black Music Month page.  Anyway, back to our front page:  In May 2021, Lloyd Price died at 88 years old.  He was way more than just a singer, you can research that on your own. But when you listen to Lawdy Miss Clawdy, think about how he was 17 years old in New Orleans in 1951, fiddling around writing music bumpers for an AM station. Luckily for all of us, a Big Producer heard him, brought him to a recording studio, and dropped Fats Domino on the piano to create R&B's record of the year. Indeed, this cut is prototype rock-and-roll, as it was one of the first songs to feature a back-beat. By 1959 and after a stint in Korea, Price had a number one Billboard hit with a song about a bar-room murder, which suffered the indignity of being censored by Dick Clark.  If you don't like Lloyd Price's voice, please return to your auto-tuned world with our regrets. Here's more than a quarter-million hits on keywords "autotune sucks".

  • The entire RadLab series, developed at the close of WWII and arguably the original canon of microwave engineering, is available in pdf.  We linked to a site that has offers the entire series of these sacred books for free. If you think that they are hopelessly out of date and you will learn nothing from them because they don't come with ear buds, go get your Six Sigma Black Belt and stop pretending to be an engineer.

  • We've added Dr. Eleanor Adair to our Microwave Hall of Fame. She performed research on the effects of microwaves on humans and animals, often using herself as a sample.  Fear not: Dr. Adair lived eighty-six years with no ill effects.

  • We added three companies to our MMIC page: ATEK Midas,  mmTron and Teramics. Welcome one and all!

  • There are some new articles available via the relatively new IEEE publication, IEEE Journal of Microwaves. Unlike most IEEE materials, this is a free publication (you can download the articles even if you are not an IEEE member). As before, articles cover a wide range of topics, including microwave history, spotlights on some microwave pioneers, and much, much more. .

  • We're always fixing typos and making fixes of one kind or another. We fixed our Marchand  balun page thanks to John C. Figure 13, the impedance variation across frequency, was incorrectly annotated.  Notice something not-quite-right? Let us know!

  • Meanwhile, on our discussion board, we've got some questions that need YOUR answers.  Here's some discussion about using choke flanges on waveguide parts in a lab envirconment. We have added to the discussion of "negative" group delay in a high-side mixer, thanks to a paper by Dr. Dylan Thomas.  Pop on over to the discussion board to register and sign in, then chime in on existing threads, or start your own topics. Our new user approval process is quick and anonymous, blocks most bots, and eliminates spam by more than 99%. At least that's what the sales rep told us...

Attention forward thinking microwave marketeers: check out information on advertising with us. Sponsorship information is but a click away...

As always, we want you to sign up for the MW101Stuff newsletter, or submit a photo for our Microwave Mortuary. We'd love to hear from you, whether you have nice things to say about Microwaves101.com or just want to tell us how we've ruined your life.
