Keithley's On-line Seminars CD

Keithley's Making Measurements with Confidence CD, which is
available free of charge, is a collection of on-line seminars on
measurement methods. This CD offers practical and helpful techniques
for obtaining the most accurate and precise measurements possible.  

For additional information on Keithley call 1-800-935-5595 or to
request your Free CD go to:  http://nls.planetee.com/t?ctl=927D:FFCBF


1.  Viewpoint
What About BPL Pollution?

Broadband communications represents a potentially high-growth market
for years to come. The infrastructure solutions for broadband
services are many, including wireless access and fiber optics, with
no clear winners. One of the more intriguing competing technologies,
broadband powerline (BPL) communications, takes advantage of the
existing powerline infrastructure to send high-speed data from point
to point and into subscribers' homes.

On the surface, it appears to be an almost ideal solution, provided
that BPL can deliver the data rates needed for true broadband
communications services. But there is concern, especially among
users of the HP and VHF spectra, including amateur radio
aficionados, from BPL radio pollution. Although not resolved, the
Federal Communications Commission (FCC) has noted in its adoption of
BPL rules last year that BPL is a source of interference for
existing HF and VHF operators. If you have concerns, please share
your thoughts by contacting me at: mailto:jbrowne@penton.com.

Rogers To Unveil New Material at MTT-S

New and improved, thinner RO4350B will be on display at the Rogers
Corp. (Rogers, CT) booth at the upcoming Microwave Theory and
Techniques Symposium (MTT-S) next month in Long Beach, CA. Designed
for high-speed digital and test applications, the new material
features dielectric loss of only 0.004, good plated through-hole
reliability, and consistent dielectric constant at various data

Active Models Support Nonlinear Simulation

Computer-aided-engineering (CAE) model developers Modelithics have
created a new nonlinear transistor library to complement their
library of capacitor, inductor, and resistor models. The new
library, which is now available for use with the Advanced Design
System (ADS) suite of CAE tools from Agilent Technologies (Santa
Rosa, CA), includes small-signal models for low-noise amplifiers
(LNAs) as well as LDMOS power transistor models for high-power
amplifiers (HPAs). The library contains models for a wide variety of
industry-leading BJT, JFET, MOSFET, MESFET, and pHEMT transistors
from major vendors, including: Cree, Agilent, Excelics, Infineon, ON
Semi, Mitsubishi, Motorola, NEC, Philips, and Rohm, with more to be
added continuously.

Salerno University Upgrades Antenna Test Lab

MI Technologies (Suwannee, GA) announced that is has been selected
by the University of Salerno (Fisciano, Italy) to supply and
commission a state-of-the-art antenna measurement, acquisition, and
analysis system for an existing anechoic chamber located on the
University campus. Under terms of the contract, MI Technologies will
install a cylindrical near-field test facility that will feature the
MI-3000 Acquisition and Analysis Software. The system will be used
to validate existing transform algorithms for optimizing the amount
of time taken to acquire near-field data using spiral techniques.
According to Dr. Carlo Rizzo, European Operations Manager for MI
Technologies, "We have just recently signed a formal agreement with
the Department of Electronics, University of Salerno, which will
allow us to share new algorithms intended to drastically reduce
acquisition time for near-field data in all three geometries
(planar, cylindrical and spherical). The University of Salerno has
an impeccable track record concerning the development of new
near-field techniques for antenna measurement applications." MI
Technologies will install the system and perform the acceptance

Report Puts Bluetooth In Driver's Seat

Bluetooth technology is replacing wire harnesses in automotive
applications, according to findings from research firm ABI Research
(Oyster Bay, NY). The company's latest study, "Dedicated Short Range
Communications (DSRC), notes that many telematics and navigation
systems over the past year have moved towards using Bluetooth. As
ABI Research senior analyst Dan Benjamin comments, "The automotive
industry regards Bluetooth as an acceptable compromise because users
get their network connectivity, while automakers do not have to deal
with installing costly cellular radios, or the hassles of managing
customer accounts or dealing with wireless carriers." But the report
states that next-generation collision avoidance systems and even
intelligent traffic systems will make use of DSRC in the form of
alternative technologies to Bluetooth.

Wireless Access Chips May Save Millions

TrueAdvantage (trademarked) Wireless Access Solutions from Agere
Systems (Allentown, PA) are networking chips that Agere claims can
potentially save wireless service providers worldwide up to $300
million per year in T1/E1, Synchronous Optical Network/Synchronous
Digital Hierarchy (SONET/SDH), and Ethernet leased line backhaul
costs. The solutions include APP network processors, a link layer
processor (LLP), and framing and mapping devices, as well as
reference designs, software, and hardware development systems. The
products enable the convergence of 2G, 2.5G, and 3G network
applications into a single solution by integrating the various
protocols. Among the first customers, 3G wireless equipment supplier
NEC has selected the Agere APP500 network processor for its wireless
access equipment.
