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 November 2020:  Remember all those conversations you had with the boss about going to microwave conferences, which always ended with "too expensive" and "maybe next year" while the company sent the Good Old Boys to all the conferences they wanted to attend? Please understand that 2020 is the year of the virtual conference. There are no travel costs associated with attending virtually, and registrations are deeply discounted. This year, just tell your boss you picked out a conference (or two) and you are going to attend it, will charge overhead for your time and will put in to be reimbursed for the registration.  Every company gains when their employees attend professional conferences.  Chances are you won't get fired for this act of mutiny, and you can put in half-time work between the talks you want to attend. Want to learn about the most-efficient >5W 4-18 GHz GaN amplifier ever designed?  IEEE BiCMOS and Compound Semiconductor Integrated Circuits and Technology Symposium (BCICTS) is fully virtual and occurs on 16-19 November.  Check it out at https://bcicts.org/, and read the Advance Program to learn about what's going down.  Registration is $275 for IEEE members, $375 for non-members, and $100 for students. Short course and primer cost are additional but still a bargain. Enter discount code "unknowneditor" to receive zero percent off of your registration!

Again, a reminder: if you need to mingle with humanity, science (and its less glamorous but harder-working cousin, engineering) insist: wear that mouth and nose diaper!


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

  • We expanded our page on mismatched terminations to include three ideas on how to make them, plus our original content on phase-variable mismatch. We even put up a page on mismatched termination power handling.

  • Breaking news! Here is market research that shows Microwaves101 is #1 in HTCC manufacturing. We predicted this would happen back in July, it is proof that many market studies are BS. But if you insist on spending $7350 to buy the data, let us know how we are doing!

  • We have a brand new page on coax cable modeling. Here you will learn how to account for connector VSWR and coax manufacturing tolerances, and specify overall performance expectations of custom cables with some level of confidence.

  • Our October featured video was from our friends over at PRFI, and shows how to calibrate an RF probe system for on-wafer testing using an impedance standard substrate  (ISS) from Cascade Microtech. In this case, PRFI's Graham Pearson is testing a wafer containing a MMIC amplifier. It's a great video that is geared toward fabless MMIC suppliers using WinCal software, as opposed to foundry production testing (which might use a sportier setup out in a clean room).

  • We're always fixing typos and making fixes of one kind or another. This time around, we fixed a typo on the S-parameter spreadsheet page, and cleaned up the discussion board a little bit.  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 designing a 100W amplifier where a reader offered some advice on stabilizing a transistor, which ended up in a successful design. Someone is looking  for references for a simple  microstrip line impedance formula.  We also have a question from someone who's having a bit of a heating problem. Do you know where someone can buy a second-hand impedance tuner? 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.
