What's new on Microwaves101?

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


Before we get to what's new on Microwaves101, there's an historic anniversary coming up.  On April 4th, it will be 50 years since Dr. Martin Luther King Jr. was killed.  Soon after that infamous event, Washington DC, Baltimore, Chicago and other US cities were literally set on fire.  Here's a short video of some inner city kids' impressions of the aftermath, and here's a recorded phone call from someone that was inconvenienced by the troubles. King's killer, James Earl Ray, fled the country and was arrested two months later at London's Heathrow Airport, when his alias turned up on a Royal Canadian Mounted Police watch list.  He was sent to prison for 99 years, and died in 1998. Hollywood has offered up a few movies on King's life (Selma, for example) but none on the riots following his death.  The closest thing is Spike Lee's "Do the Right Thing", which was chastised by the media, claiming it would inspire violence.  Movies don't inspire violence, but senseless murders often do. Today we seem no closer to King's Promised Land than we were during his last speech

And now, it's time to see what's new on Microwaves101 for February/March 2018:

  • Another foundry was added to our MMIC page, Advanced Wireless Semiconductor Company. It is a pure-play foundry, located in Taiwan.  Think of it as a competitor to Win Semi.

  • Speaking of MMICs, did you hear the news? After being denied the sale of the "Wolfspeed" carve-out of RF products to Infineon for $850M back in early 2017, Cree announced on 26 March 2018 that they turned the deal around and will be buying Infineon Technologies AG Radio Frequency Power Business for $425M.  Maybe between these two companies the dream of selling solid-state microwave ovens will finally be realized...
  • We have a new page on right-angle resistors. Recall Microwaves101 Rule of Thumb #54, which states that a right-angle resistor should count as half of a square in a meandered resistor.  We analyzed it two ways, and came up with a more accurate value of 56% of a square.

  • In addition to our recently new page on planar RF baluns, we have a new page on the Marchand balun. Here you will learn a little history of the trade journal Electronics.  In addition to publishing Marchand's original paper, Electronics published an article by Gordon Moore back in 1966, which also has enduring value.

  • We added Nathan Marchand to the Microwave Hall of Fame. He earned scores of microwave-related patents over a long career, and was a published IEEE author and Fellow. His main interest seemed to be radio direction finding, if you look at his inventions.  There is not much info available on Marchand on the world-wide web, but thanks to the IEEE archives we have a short biography and a photo of him.

  • On our Where-Are-They-Now page, we have updated entries for Lark RF Technology (known for RF filters) and Film Micro-Electronics (FMI).

Attention forward thinking microwave marketeers: check out information on advertising with us. Sponsorship information is but a click away... come and share the magic of 15,000 page views per weekday. Hey that rhymes!

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.
