.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 October 2020:  While we suffer through the month of surprises, keep your eye on the prize: Halloween!  Maybe your kids can't go trick or treating this year, but you could stay home and watch horror movies. If you like vengeance (seems like a political theme for the past few years), a personal favorite is Pumpkinhead. In today's cinema experience of rehashed ideas and merchandising, it is quite amazing that this B movie, released in October 1988, started as a poem.  For another example of a poem that spawned a horror flick, check out The Raven by Edgar Alan Poe. Here's the classic 1963 version with Vincent Price, Peter Lorre and Boris Karloff. Here's the 2011 version with John Cusack. All available on Amazon, and note that you have to pay a buck more for Vincent Price versus John Cusack.

Again, a reminder: if you need to mingle with humanity, science (and its less glamorous but harder-working cousin) say clearly: wear a mask.

Meanwhile, what's new at Microwaves101 for October 2020?

  • We have a new page on mis-matched terminations, which are often needed for acceptance testing of power amplifiers and transmitters. Maybe next month we'll show you how test your SSPA or transmitter "at all phase angles" without having to buy a line stretcher.

  • We found a discarded patent disclosure for a three-bit attenuator example in a box that was heading for the recycle bin, so we rescued it and threw it on the site.

  • Our September featured video was from Grey Beard Microwave.  He shows us how to analyze a coax short circuit using Microwave Office Analyst 3D EM solver, then shows us how to design a microstrip short circuit which would be good enough for a calibration standard. Bravo!

  • Coax cutoff frequency was split off from our main coax page. Going forward we will be chopping up a lot more pages to help stay on topic.

  • On our where-are-they now, we note that New Hampshire's Thunderline Z became part of Fusite in 2000.  This acquisition also ties them to Emerson, who has owned Fusite since 1972. Thanks to Cheryl! We further note that Ion Beam Milling (also in New Hampshire, was acquired by Semigen in 2018. 

  • We added a new animation to our polarization page, courtesy of AI Linux. Here you can see linear, circular an  (for once) elliptical polarizations. Thanks to Hadrien for obtaining permission.

  • The end of August 2020 marks the 20th anniversary of Microwaves101 presence on the web. The Unknown Editor (and his supreme helper) provide some historical background, and explain what  We Ain't Been Slack Cap'n Walker is all about to people who were not in on that joke.

  • We're always fixing typos and making fixes of one kind or another. We fixed a mathematical typo on our TRL calibration page which was pointed out by an alert reader. Notice something not-quite-right?  Let us know!

  • Meanwhile, on our discussion board, we've got some questions that need YOUR answers.  Here's a discussion on the relative merits of 1.85mm and 2.4mm connnectors.  These are compatible connectors, why would anyone buy a 1.85 to 2.4mm adaptor?  Pamela is looking for information on what her Dad, John R. P. Bordenave, worked on ith the 60's and 70's. Like many engineers, he was not allowed to talk much about his work. 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 or just want to tell us how we've ruined your life.
