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

If you work in a cash-squeezed company (gotta pay those investors!) it's time to gather around a fifty-gallon drum out in the parking lot, fill it with flammables, light it up and and warm your hands.   Pass around a hip flask and pretend that you are at party.  Or perhaps you will receive a thoughtful and generous a bonus like Clark Griswald did...   Happy Holidays from Microwaves101!

Now let's see what's new on the Microwaves101 site for December 2018...

  • We have a new page on charge storage capacitor dissipation, noting that capacitor heating is a reliability issue you want to avoid. It is basically a re-do of a previous page that had some problems. This time, we've posted an accompanying charge storage  spreadsheet in our download area that will help you calculate charge storage needs, select your capacitor bank, and calculate dissipation due to ESR. When troubleshooting any electronics, tell your co-workers "it's the capacitor, stupid" and they will soon know you are an electronic genius. 

  • We have some glamour shots of a vintage distributed amplifier, thanks to Bruno from Italy.  We are hopeful that the amplifier gets repaired so we can see measured performance. Don't forget to replace those fifty-year-old caps!

  • On our filter response type page, we generated ideal high-pass filter responses for each type, with filter order swept from 3 to 5 so you can compare the skirts.  We also plotted group delays.  For these analyses we used filter elements that are built into Microwave Office, a huge shortcut! Be sure to click on the tiny graphs to see them in all their glory....

  • We have a Smith chart cake on Smith chart page, thanks to Dr. Raghavan and his students at NIT Trichy. Enjoy!

  • Four acronyms dated from WWII were added to our slang dictionary, thanks to Arne. Fair warning, the F-word is involved...

  • We sent out two of the infamous Unknown Editor pocket knife keychains this month, one to John in the Netherlands, and the other to Bruno in Italy.  Keep the comments, updates, and suggestions coming!  This is one of the many ways we continue to improve the site.

  • We still have last month's Unknown Editor column posted,  "what's so funny about peace love and understanding?"  He claims he's got some ideas for new content in 2019...

  • Other fixes and updates:

    • We found out what "EMT" stands for as in Microwave Hall-of-Famer E.M.T. Jones. Thanks for solving this mystery, Dr. John!
    • There's a new link to another free PCB software site.  Thanks for the heads up, Titus!
    • An update to the Where are They Now? page came in from a contributor who wishes to remain anonymous.  Thanks, unknown contributor!
  • Meanwhile, on our discussion board, lots of stuff needs your attention.  Remember, it's December, and no one is expecting you to be doing any real work, and what better way to celebrate the holidays than to help out a newbie? Someone is talking about exceeding the stable gain of a device, Here is a question about how to avoid gain suckouts due to drain supply connections on a MMIC distributed amplier.  A MW101 newcomer looking for resources to help him with a low-gain, flat bandwidth amplifier. Someone has a simple question about waveguide.  Here's a question about uniformity of electric field along a gap capacitor. Let's see if we can't give them a hand!  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 and eliminates spam by more than 99%. At least that's what the sales rep told us...

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.
