       Four Steps For Making Better Power Measurements

Before you select a power meter and its associated sensors, it's
important to understand the factors that can influence the quality of
your power measurements.  These factors affect the accuracy, economy
and technical match to your application.  Click on the link below to

1.  Viewpoint
Finding A Place For Technology

When so many companies flocked to making GaAs integrated circuits
(ICs) in the early 1980's, most thought that the advantages of the
technology over silicon bipolars in terms of speed and frequency were
enough to ensure healthy sales and unbridled success. Unfortunately,
few technologies will sell themselves unless the price tag is also
reasonable. One of those technologies apparently looking for a home is
ultrawideband (UWB), a marvelous concept with the capability of huge
data rates at low transmit and power-consumption levels.

As promising as UWB technology appears "on paper," however, it is
competing with hordes of other wireless technologies, including
Bluetooth and WiMAX. A report from IMS Research reviewed in this
week's newsletter cites mobile telephones as the place for UWB. And
UWB may yet prove to be a multimedia cable replacement for big-screen
televisions and their peripherals. But for all its magic, it must be
produced cheaply enough to make sense, and only then will it be widely

AWR and Peregrine Team On Process Design Kit

Software specialist Applied Wave Research (AWR) and device supplier
Peregrine Semiconductor have announced the availability of a process
design kit (PDK) for Peregrine's UltraCMOS complementary metal oxide
semiconductor (CMOS) silicon-on-sapphire (SOS) process in AWR's Analog
Office(R) suite of high-frequency software design tools. The PDK is
the first step in a long-term collaboration between the two companies
to deliver complete radio-frequency integrated circuit (RFIC) design
solutions. The PDK will help shorten IC development cycles, accelerate
tape-out to the Peregrine process, and speed wireless products to
market. According to John Sung, Peregrine's director of CAD
engineering, "After using Analog Office during the PDK development
process, our designers were impressed with the tight electrical and
physical integration, ease-of-use, and the environment tailored for
high-frequency RF designers. The PDK includes a complete set of
validated schematic symbols, simulation models, and fully
parameterized layout cells that are characterized to match the
UltraCMOS process performance."

Jacket Micro Devices Awarded Patent

Jacket Micro Devices has been granted United States Patent No.
7,068,124 for their passive multilayer circuit technology. Issued for
the publication of "Integrated Passive Devices Fabricated Utilizing
Multi-layer Organic Laminates," the patent was awarded to Jacket Micro
Devices' founders for their invention of a key technology used in the
company's multilayer organic packaging technology and module
production process. According Dr. George White, the company's founder
and Chief Technology Officer (CTO), "This invention embodies for the
first time an organic device that is realized through the design and
fabrication of the highest quality 'Q' factor passive components which
can be integrated in a multilayer organic printed circuit board. We
are excited to see the fruits of years of research into advanced
packaging technology we began at Georgia Tech." Dr. White added
"Integrated passive devices using these techniques are able to meet
the specifications of cavity and LTCC filters with equivalent or
better performance in smaller footprints."

Microwave Circuits' Filters Aid Commercial, Military Systems

Microwave Circuits, Inc. (Lynchburg, VA) has developed an extensive
line of miniature and high-power bandpass, lowpass, and high-pass
filters for commercial and military applications. For example, model
B6830004 is a miniature bandpass filter with maximum insertion loss of
1.3 dB at its 3-GHz center frequency. Peak-to-peak passband ripple is
within 0.5 dB. Rejection of unwanted signals is more than 60 dB from
DC to 1.5 GHz and more than 60 dB from 4.5 to 18.0 GHz. The bandpass
filter measures just 0.45 x 1.00 x 2.75 in excluding connectors. The
company has also developed patent-pending ceramic-loaded tunable
cavity filters that are a fraction of the size of standard
quarter-wave cavity filters.

Report Sees Steady Growth For UWB In Mobile Phones

A new research report from IMS Research, "Worldwide Market for
Ultra-WIdeband," projects that ultrawideband (UWB) devices will
achieve low-volume penetration into the mobile telephone market in
2007, rising to a penetration rate of around 20 percent by 2011. The
mobile phone market is likely to be an important market for UWB for a
number of reasons. The sheer size of the available market means that
even if relatively low penetration rates are achieved, there is a huge
potential market for UWB. The potentially negative effect of cellular
terminals on markets such as PDAs, MP3 players, and digital cameras
only heightens the importance of the cellular market to the future of
UWB. According to Fiona Thomson, Market Analyst for IMS Research, "The
sharp rise in the number of feature phones and smart phones has meant
that the demand for extra connectivity is becoming an extremely
crucial factor. We see smart phones adopting UWB first with feature
phones following around 12 months later."

Linear Launches Low-Power 14-b, 125-MSamples/s ADC

Linear Technology Corp. has unleashed the LTC2285, a 14-b, 125
MSamples/s dual high-speed analog-to-digital converter (ADC) that
dissipates just 395 mW power per channel. With signal-to-noise ratio
of 71.3 dB and spurious-free dynamic range (SFDR) of 78 dB at 140 MHz,
the ADC is ideal for digitizing the intermediate-frequency (IF) stage
of wireless receivers, including in WiMAX systems. The high sampling
rate allows designers to capture wider bandwidths and increase the
capacity of existing systems that are currently sampling at 65

Rogers Launches Advanced Flex Circuit Material

Materials specialist Rogers Corp. has announced the availability of
its R/flex JADE(TM) series of flexible circuit materials, the next
generation of the firm's R/flex CRYSTAL(R) epoxy adhesive system. They
are lead-free solder capable, for RoHS-compliant designs, and they
meet flammability requirements without the use of halogen. They
feature a high glass transition temperature making them suitable for
high-yield, multilayer circuits. The transparent adhesive system
simplifies visual inspection.
