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 World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Chipworks Press Release - October 13, 2011
Chipworks Posts Teardown Images of Apple iPhone 4S
-- Images and analysis to be updated continuously on
iFixit web sites.
Ottawa, Ontario, October 13, 2011 –
Chipworks announced it has posted initial results of its
Apple iPhone 4S teardown and will continuously update images and information as it comes out of its labs over the
next 48 hours. The focus of this analysis is on the die level to provide information that is not readily available
at the board level.
Images and information from the teardown will be posted at
http://www.chipworks.com/en/technical-competitive-analysis/resources/recent-teardowns, and select images are
being shared with iFixit at
full analysis will be available on the Chipworks website including de-capsulated images of the chips in the iPhone
4S, die layouts, and information on the process technology used to build some of the devices.
4S contains a lot of the same devices observed in the iPhone 4 and the iPad 2 making this somewhat of a technology
hybrid between the two,” says Jim Morrison, Product Manager at Chipworks. “We're going to be looking deeper to
confirm other similarities and differences. For example, we will confirm whether the A5 chip found in the iPhone
4S is still being fabricated by Samsung or has been moved to TSMC's 40 nm low power process.”Chipworks is the
recognized leader in reverse engineering and patent infringement analysis of semiconductors and electronic
systems. The company's ability to analyze the circuitry and physical composition of these systems makes it a key
partner in the success of the world's largest semiconductor and microelectronics companies. For more information,
