What's new for January 2010?

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

Finally the Lost Decade is over, now let's all get back to work and pick up the pieces!

• We continued our quest to make a more usable phase shifter resource, hopefully we'll keep at it for another month before we get distracted. The main page has been redesigned, and we've added several new ones. There's a page that reveals an important characteristic of phase shifters for phased arrays. To be Fair and Balanced like Fox News, we've added a page on MEMS phase shifters...
• We have a page on how to drive multistate simulations of digital phase shifters using Agilent's ADS. Just try to find this information somewhere else on the world-wide web!
• Speaking of phased arrays, we've started separate pages on PESAs and AESAs, with almost zero content (feel free to contribute)! However, we humbly suggest you take a moment and go to our PESA page to see an alternate, solid-gold origin of the word...
• As for AESAs, we've started a page which will eventually explain some of the tradeoffs for common-leg circuits which are sometimes used in T/R modules. We also started a page on true time delay networks.
• Thanks to Justin, we have have a new page explaining how to feed a global positioning system (GPS) antenna with right hand circular polarization (RHCP).
• We have started a parallel plate waveguide page. Did you know that PPW supports TEM mode? It turns out that this media is an enabler for teraHertz systems.
• Speaking of waveguide, have a cartoon of what not to do with a rectangular waveguide, thanks to JB. Let's get some more microwave cartoons going, everyone!
• In the microwave mortuary we have some new images from Karol, who is from Gdansk. A cratered FPGA chip, some melted capacitors, and a blown IGBT brick. Nice Christmas colors!
  
• The Unknown Editor tried desperately to come up with some encouraging remarks on the close of the past,"lost" decade. Most of you must agree, this exercise was doomed to failure...

We've got some new questions--and answers--on our Microwave Message Board. We've have hundreds of topics posted on various microwave engineering subjects, with many more replies; our message board is an industry resource. Post your own questions, or help us answer some of the ones that are already posted. Some of the posted material may eventually get captured in our encyclopedia, so do your part for posterity! We'll remove any postings that we consider inappropriate.

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 10,000 page views per weekday. Hey that rhymes! Join our best friends in the Virtual Lobby!

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!
