About RF Cafe

BSEE - KB3UON
RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

There are 1,000s of Pages Indexed on RF Cafe !
These items are an archive of past Topical Smorgasbord items that have appeared on the RF Cafe homepage. In keeping with the "cafe" genre, these tidbits of information are truly a smorgasbord of topics. They all pertain to topics that are related to the general engineering and science theme of RF Cafe. Note: There is also a huge collection of my 'Factoids' (aka 'Kirt's Cogitations') that might interest you as well.
You Know It's Really Bad Out There When...
(source: Design News)
|...czar of all things analog, Bob Pease, gets laid off. That is not a typo. I was just kidding when I made a comment about National Semi's massive layoff headline a couple days ago. Now, Design News confirms it. If Bob is most famous for his seemingly unlimited knowledge of analog circuits, he is second-most famous for his disdain for computers and simulations. He sketches circuits in his head, then transfers them to napkins and envelopes... and they work. Bob's monthly articles will continue.|
I Read Through the List
(source: NY Daily News)
|By now we have all heard of infamous financier Bernard Madoff and his multibillion dollar scam that left a few thousand people broke. When the list of victims was releases the other day, I searched through it for electronics industry notables. The only one I found was Keystone Electronics Corporation Employee Profit Sharing Trust (page 74). It does not say how much they lost. So, if you order parts from the good people at Keystone Electronics, be especially nice to them; they are living with the results of bad decisions by those they entrusted with their well-being.|
What Will Be
"The Next Big Thing?"
(source: Electronic Design)
|This chart shows the cycles that the electronics industry has experienced from 1970 through now. Mainframes, PCs, cellphones, and consumer apps defined the peaks. We are now in the right-most nadir. The extrapolated curve predicts "the next big thing" waiting somewhere. Some say it will be alternative energy technologies. Others say medicine. Your Opinion|

|This interactive map displays RFID deployments in different parts of the world. The goal is to show how widespread RFID adoption has become, and to help you find information regarding deployments relevant to your own RFID applications. You can add deployments not currently on the map by filling out the form on RFID Journal's webpage.|
the Key to Cloaking
(source: Scientific American)
|The stuff of science fiction gets farther from fiction and closer to fact every day. Such is the case with advances in cloaking technology. A mere 4-5 years ago cloaking required special cameras and props - more like magical illusions. Now, structures are being developed with negative refractive indices that can cause microwaves and visible light to wrap around objects as if they were not there. The scale is small now, but then the Chinese's first rockets were finger-size and Kilby's first IC had a single transistor, resistor, and capacitor.|
Which Display is Greener:
CRT or LCD/Plasma?
(source: LA Times)
A lot of people believe that switching from their old energy hog CRTs to a nice new high-definition flat-screen TVs and computer monitors
is the neo-responsible thing to do. Not so according to results of a study by the CEC.
* Average size TVNews stories have appeared recently where governments are seeking to ban large plasmas.
Does One Twitter or Does One Tweet?
|There seems to be some misunderstanding of the proper verb for describing what one is doing when using the Twitter.com website. Do you twitter, tweet, or something else? Inc. magazine went to the source to find out. According to co-founder Biz Stone, "Ultimately, whatever gets used more will probably win out, but my personal thought is the Twittering is the verb that refers to the act of creating a tweet, which is the noun. However, you may catch me tweeting one day, so don’t hold me to that."|
Best Engineering Colleges by Salary Potential
|It is no secret that the school from which you hearken can make a difference in opportunities that avail themselves to you. It is akin to owning an academy ring as an officer in the armed services. Experience eventually overrides pedigree if you are outstanding in your field, but let's face it, having an advantage from the start can really make the upward climb easier. PayScale.com has collected the data. #1 for fresh-out: CIT; #1 for mid-career: MIT.|

Prismark, for which I have much respect, has issued a "2009/2010 Short-Term Outlook" report summarizing their prediction for the electronics
systems and components markets. Basically:
* Overall electronic systems
market to decline at least
12% in 2009 (largest ever),
modest growth in 2010
* The last electronics
recession occurred in
* Semi industry declined 2.8%
in 2008, 23% expected for
2009, recovery in late 2010
* 2009 IC volumes to drop to
* PCB industry declines by
16% in 2009, recovery to
2008 levels by 2012
