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 September 2021: Welcome back to school. Unfortunately, we still have an unwelcome "visitor" and you must prepare for another round of Covid infections.  In the news, 15 employees in one school district died from Covid over the course of ten days. If your school district wants your kids to wear a mask, don't be the guy with the zip ties.  To all anti-vaxxers reading this message, the rest of us are getting tired of the situation when the solution is at hand. Pretty soon you will get sick of being denied access to events, being unenrolled from college,  surcharges on your insurance, and loss of income. Remember when HR enquired about your vaccine status? It was not just  idle curiousity...  just get vaccinated, like the Continental Army under George Washington. Do something for humanity, for once in your life.

Meanwhile, what's new at Microwaves101?

  • We offer new page on equal-ripple transformers. We posted an example of a 2-18 GHz transformer showing how performance improved as sections are added. You can make your own equal-ripple transformers using The Professor's Transformer spreadsheet that you can download for free from this site. Seriously, let us save you a week's worth of work, you need time to do all of the Fall things: pick a medical plan, figure our your HSA and dependent care contributions, summarize your "accomplishments", complete your individual development plan, review your career with your boss and learn about the latest recycled company initiatives. On second thought, working out equal-ripple math seems like a vacation compared to that stuff...

  • We've added Wilhelm Cauer to our Microwave Hall of Fame. Don't be the Ugly American when you pronounce his name, it's "vihl-helm," not "will-helm".  Cauer is a bit of a tragic figure, losing his (civilian) life for no reason during the fall of Berlin in 1945.  He made an enormous contribution in RF engineering, moving the industry from analysis to synthesis. When you solve for an equal-ripple filter using Chebyshev polynomials, that is something that he did first. Why isn't Pafnuty Chebyshev in the Microwave Hall of Fame?  We'll get back to you on that obvious blatant omission...

  • Wilhem reminds us of an ancient joke that goes like this: 9W is the answer to what question?  Mr. Wagner, do you spell your last name with a "V?"

  • Our Stuffies of IMS contest is over, no one submitted an answer as to the companies that give out the plush toy swag. Maybe that is an indication of how much of our audience actually attends conferences....So here the Unknown Editor (and perhaps mostly his faithful helper) reveal the secret stuffy identities.

  • Our embedded resistor page has some new images showing how to process them, thanks again to Tom!

  • We added "wobulator" to our portmanteaux dictionary. Wobble oscillator!

  • In August we added a video on spectral inversion. It was produced by an amateur radio enthusiast and shows what happens to audio when it gets inverted (and how to recover it). The same principles apply to microwave radio and radar signals, but hearing the audio really drives home the point.

  • We're always fixing typos and making corrections of one kind or another.  Notice something not-quite-right? Let us know!

  • Meanwhile, on our discussion board, we've got some questions that need YOUR answers. N2HMM is looking for help identifying a microwave tube.  Imtiaz is having troubles with multi-line TRL calibrations...  Pop on over to the discussion board to register and sign in, then chime in on existing threads, or start your own topics. Our 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 or just want to tell us how we've ruined your life.‚Äč
