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...

Analog Devices Press Release - November 10, 2011
Analog Devices Introduces Highly Integrated Octal and Quad ADCs for
-- High-speed A/D Converters Feature More Channels, Lower Power and Smaller Package Size
Demanding Medical Imaging and Communications Applications
Mass.--( BUSINESS WIRE)-- Analog Devices Inc. (ADI), a
global leader in high-performance signal processing technology, announced today the addition of four high-speed
A/D data converters to its market-leading data converter product portfolio. The two octal- and two quad-channel
converters are designed for medical imaging and communications applications where the combination of high channel
density, low power and small size provide systems engineers with greater design flexibility and lower per-channel
cost for data conversion.
AD9257 14-bit and
AD9637 12-bit octal A/D converters each integrate eight
A/D converters into one package and feature 40 percent lower power per channel than other discrete octal
converters. Analog Devices today also introduced the
AD9253 14-bit and
AD9633 12-bit quad A/D converters in 48-lead chip-scale
packages that are more than 10 percent smaller than competing devices.
Data Conversion for Medical Imaging
All of the new converters support the higher channel
densities of MRI (magnetic resonance imaging) systems, medical ultrasound and other high-end imaging applications,
such as industrial visual inspection systems and non-destructive ultrasound. The AD9253 14-bit and AD9633 12-bit
quad A/D converters are offered in a non-magnetic package and can be used safely within the magnetic field of an
MRI system. This allows the converters to be placed closer to the signal of interest, which can increase the
quality of image resolution and image throughput while reducing the overall component count.
components for these high-speed converters include the AD8334 quad, ultralow noise VGA (variable gain amplifier)
for ultrasound applications.
Data Conversion for Communications
The new octal and quad A/D converters are also suited to MIMO-based (multiple-input, multiple-output)
radios, 3G infrastructure equipment and other wireless communications applications.
ADL5202 variable gain wide bandwidth amplifier,
AD8376 ultralow distortion IF dual VGA and
ADA4937 ultralow distortion differential ADC driver work well with these high-speed converters in
