1.  Viewpoint

Dealing With The Expansion of UWB

Ultrawideband technology (UWB) is typically associated with short-range,
low-power, high-data-rate communications. By sending and receiving a
stream of time-sequenced pulses, low-power transmitters and receivers
can process data rates in excess of 100 MB/s over short ranges. It is
this combination of characteristics and capabilities that make
"carrier-free" UWB technology so attractive to product developers for
the "wireless home." Designers working with video products, such as
high-definition-television (HDTV) monitors and peripherals (DVD players
and recorders), can envision complete home-office and home-entertainment
centers in communication without wires.

But what about UWB technology for radio-frequency-identification (RFID)
tags? Late last year, Multispectral Solutions
( http://nls.planetee.com/t?ctl=33FC:F3175 ) proposed UWB as an optimum technology
for RFID tags, based on the company's MSSI PAL650 tagging system, which
was approved for unlicensed use in the summer of 2003. The system
provides a range of 600 ft. under line-of-sight (LOS) conditions, with
real-time tracking capability within 1 ft. Compare this performance to a
typical range of 300 ft. for conventional active RFID tags/readers and
less than 30 ft. for traditional passive RFID tags.

Of course, the proliferation of UWB technology in the home and for
industrial applications as RFID tags depends upon reliable measurement
solutions. For now, oscilloscope manufacturers are pushing their
products towards 100-GHz bandwidths in order to handle the test
requirements of tracking UWB signals and their higher-order harmonics.
But frequency-domain UWB testing is not trivial and may require a total
new approach to microwave measurements.

M/A-COM Introduces RFID Line

Microwave and millimeter-wave component and subsystem supplier M/A-COM
announced its "RFID by M/A-COM" Series, a line of specially designed
RFID components including circulators, IQ modulators/demodulators,
antennas, and amplifiers for use in RFID applications. The initial
product line in the series is a new range of ferrite circulators
specifically designed for the RFID reader market. The new ferrite
circulator series offers typical insertion loss performance of 0.21 dB,
isolation of 29 dB, and return loss of 28 dB, over frequency ranges of
860 to 872 MHz (Japan), 950 to 956 MHz (US), and 902 to 928 MHz (Europe)
for the various RFID markets. According to Joe Thomas, vice president of
M/A-COM's Integrated Products Group, "our broad development experience
in microwave and millimeter wave components meets the critical
requirements of the rapidly growing RFID market."

TriQuint Throws Support To WiMAX Forum

TriQuint Semiconductor, a leading chip and IC supplier for wireless
products, announced its support for the WiMAX Forum, an industry-led
organization that promotes the interoperability and certification of
these products based on the IEEE 802.16 standard. The WiMAX Forum
attempts to create economies of scale made possible by standards-based,
interoperable products that drive price and performance levels not
achievable by proprietary approaches. WiMAX technology is designed to
help service providers across global markets deliver economical
broadband data, voice and video services to both residential and
business customers. According to TriQuint Vice President Mike Sanna,
"the WiMAX Forum is one of the best ways to support open standards that
benefit the marketplace while stimulating the development of new
products based on the IEEE 802.16 standard."

Agilent Launches 1-GHz Portable Scope

As part of a line of new digital-storage/mixed-signal oscilloscopes
(DSOs/MSOs), Agilent Technologies has introduced a portable instrument
with 1-GHz bandwidth. Known as the 6000 series, the 12 portable scopes
include models with bandwidths of 300 MHz, 500 MHz, and 1 GHz,
high-resolution XGA screens and the company's patented MegaZoom III
display technology (with 256 levels of color-intensity grades), as much
as 8 million points of waveform memory (as an option), and sampling
rates to 4 GSamples/s. Versions are available with two or four DSO
channels and as many as 16 MSO channels for evaluating multichannel
embedded systems. The 6000 Series portable oscilloscopes come standard
with LAN, GP-IB and USB interfaces as well as an additional front-panel
USB port.

AIA Tasks US Government To Support Aerospace Job Training

The Aerospace Industries Association (AIA) announced this week that it
is endorsing legislation that would task the federal government with
addressing a looming shortage of qualified workers in the sector. The
bill, sponsored by Rep. Vern Ehlers (R-Michigan) directs 11 federal
agencies, led by the Department of Labor, to form a task force for the
purpose of developing strategies to expand public and private aerospace
job training programs. The Ehlers bill (HR 758) specifically requires
the task force to report to Congress each year on the status of federal
policies and partnerships designed to advance training programs in the
areas of science, engineering, technology, mathematics, and skilled
vocational trades. According to AIA President and CEO John W. Douglass,
 "this legislation would bring together the most talented minds in the
federal government to produce a national plan for increasing the number
of students who choose aerospace-related scientific or engineering

Linear Technology Embraces Lead-Free Initiative

Integrated-circuit (IC) supplier Linear Technology announced that all of
the company's products are now available in lead-free versions as an
ordering option. Part of the company's commitment to meeting the
European Community's Reduction of Hazardous Substances (RoHS)
guidelines, the firm adopted Matte Tin as the optimal plating for
lead-free products. The company's engineers believe this provides the
best drop-in replacement since it has the lowest reflow temperature of
the lead-free alternatives, has excellent solderability performance, and
provides excellent quality and reliability. Linear Technology will
continue to offer solder plated products as well, with unique part
numbers for both the lead-free and solder plated versions.

Global Information Technologies Sponsors 33rd Iditarod

The 33rd annual running of Alaska's Iditarod dog-sled race is being
sponsored by Global Information Technologies. The firm has donated a
complete complement of Iridium Satellite equipment and airtime,
including handheld satellite telephones and pagers, for the 1000-mile,
cross-Alaskan race that begins on March 5th. The satellite-based
communications equipment provides race officials and the volunteer
community communications to contact air, headquarters, or field command
posts from anywhere on the trail in areas where no other form of contact
is possible. According to Stan Hooley, Executive Director for the
Iditarod, "The Iridium satellite communication ability greatly increases
the safety and security for both the mushers and our team of volunteers.
Global Information Technologies has definitely filled a critical need
which allows us to provide the best communication solution available for
remote locations."

RF Micro Devices Unveils Tiny WCDMA PA Module

Chip supplier RF Micro Devices announced their model RF5198 high-power,
high-efficiency linear power amplifier (PA) module for WCDMA handset
applications. Said to be the world's smallest linear PA module to
include an on-chip power detector, the RF5198 measures 3 mm by 3 mm and
0.9 mm high in a QFN package. By incorporating the power detector
technology on-chip, the RF5198 significantly reduces design complexity
and streamlines the handset design process, thereby enabling handset
manufacturers to quickly bring their advanced products to market. The
RF5198 GaAs HBT module, which provides +28 dBm linear output power with
43 percent linear efficiency from 1920 to 1980 MHz, is designed for use
as the final RF amplifier in WCDMA handheld equipment.
