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



New for February 2020:  We're deeply saddened to hear of the loss of two members of the microwave engineering community, Dr. Mojgan Daneshmand and Dr. Pedram Mousavi, along with their two young daughters, in the recent airplane tragedy in Tehran. They were both professors of engineering at University of Alberta, and active in both IEEE Antennas and Propagation Society and IEEE Microwave Theory and Techniques Society.  Our deepest condolences to their extended family, friends, students, and colleagues.  You can read more over on the IEEE Antenna and Propagation page, or read a tribute to them in the Alberta newspaper.  Watch a lengthy tribute by the University of Alberta here. You can donate to a fund set up at U-Alberta that will support a graduate student scholarship in their names. It is a little complicated to donate if you are in the United States, you have to use snail mail, but the address is on the donation page.  Please consider joining Microwaves101 in donating to this worthwhile memorial fund.



It's leap year again. Here at Microwaves101, we think leap day should be a work holiday, so The Man doesn't get an additional day's work out of us. Besides, having an extra day in the year is a headache for the payroll department. Why not help them out and take a day off? Friday February 14 is a day for climate strike in London.  If we were there we would surely join them.

It's Black History Month. The city of Tulsa is "celebrating" by looking for mass graves where bodies were dumped following the 1921 Greenwood massacre. There's a microwave connection here: ground-penetrating radar is being used to look for "anomalies". Learn more about the massacre here, including how insurance companies classified it as a "riot" so they didn't have to pay.

Congratulations to Custom MMIC Design Services,  Qorvo announced they will acquire CMDS and Decawave in a reported $500M buying spree. Let the Big Company Games begin, as the most mediocre employees scramble toward top positions!

What's new at Microwaves101 for February 2020?

  • We have an excellent new page showing a detailed example of broadband, four-way and eight-way Wilkinson power dividers, thanks to Alexander.
  • We added Guerrilla RF and Xiamen Sanan IC to our list of MMIC suppliers. 
  • We offer some updates on simultaneous transmit and receive, mostly thanks to Chris.
  • We have some updates to where are they now page... CMDSAWR (now part of Cadence) and Herley. We've also added a press release on HE microwaves's 2004 move from Arizona to Mexico. Thanks for the info, Terry!
  • Does anyone have any info on Lectronic Research Labs (LRL) and who inherited their products? They used to make a kit for budding microwave engineers.  Microwaves for Everyone was the manual, we'd love to get permission to post it.
  • In the spirit of SCIFs being in the news in 2019, the Unknown Editor has written a piece called SCIF life.  Ever wonder about the glamour of working in a SCIF? This will tell you what you are missing. Hint: it sucks.
  • We're always fixing typos and making fixes of one kind or another.  And thanks to an alert Air Force employee, we will be upgrading our SSL certificate fom TLS 1.1 to 1.3.  If anyone ever gets blocked by a notice that Microwaves101 is not a secure site, please let us know!
  • Meanwhile, on our discussion board, we've got some questions that need YOUR answers. Paul is looking for a source of WR8 guide and flanges.  Oz is looking for a copy of a classic article on tandem combiners and phase shifters from Microwave Magazine, back in 1965. GTEE19 is looking for advice on EDA products.  There's an interesting discussion going on about high frequency signals.  And, believe it or not, our own Unknown Editor has been visiting the boards, contributing his own two cents to Coax Loss and Phase. 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.
