Attend a free Agilent HSDPA eSeminar

Design and test engineers now have to consider the dynamic nature of the
new HSDPA channels. Complex parametric testing is required to verify
HSDPA functionality and performance in the UE. Learn about the main
changes that HSDPA introduces and the test implications during UE design
and RF test. Enroll now.

Making the Most of Your Website

Few editorial pieces have stirred readers' interest more than the recent
article reviewing ( "Tracking the Top 25 Microwave Websites," Microwaves
& RF, December 2004, p. 33 and online at http://nls.planetee.com/t?ctl=DE1:FFCBF ). As has
become apparent from the many calls, letters, and e-mail responses,
high-frequency engineers are passionate about their own web sites and
willing to discuss their graphical and information approaches at great
length in the hopes of finding ways to improve their sites. The article
included a sidebar story, "Top Engineering Website Turnoffs," that also
listed more than 10 steps not to follow when implementing a successful
engineering website.

Unfortunately, that December issue story only covered 25 companies,
although many more were deserving of mention. Because of the sharp
cutoff, this newsletter will explore additional sites through a new
feature section called simply WebWatch. Each issue will highlight
another website of interest, complete with comments on why the site is
noteworthy or outstanding. And, of course, if there is a website you
would like us to view, please let us know.

Agilent Sets Jitter Measurement Mark

Introduction of the 83496A multirate optical/electrical clock-recovery
module for the Agilent 86100C Infiniium digital communications analyzer
(oscilloscope) sets new standards for measurement jitter. With less than
300 fs root-mean-square (RMS) jitter, low-level measurements of clock
and data signals are possible over a continuous bandwidth of 50 Mb/s to
13.5 Gb/s. Developed in close collaboration with Agilent Labs, the
module features a continuously adjustable loop bandwidth from 30 kHz to
6 MHz for jitter testing across a wide range of industry
telecommunications and data communications standards. Pricing for the
module starts at $18,000 and for the oscilloscope mainframe starts at

Lucent and FCI Demonstrate 25 Gb/s Data Over Backplane

By combining the AirMax VS connector system from FCI and a new signaling
architecture from the Bell Labs Division of Lucent Technologies, the
companies were able to demonstrate a 25-Gb/s data transmission over a
conventional electrical backplane connection. By operating at more than
twice the data rate yet achieved over electrical backplanes, the new
approach holds the promise of achieving true 100-Gb/s Ethernet (4
channels at 25 Gb/s) performance over electrical backplanes. The
signaling technology involves duobinary signaling in which three
electrical signal levels are used to represent binary code in a data
transmission. According to Jeffrey Sinsky, lead researcher on the
duobinary effort at Bell Labs, "we are always looking one step beyond.
In order to demonstrate 25 Gb/s, we needed a connector with carefully
controlled impedance characteristics, which prevents signals from
bouncing back and forth, plus low crosstalk." The connector employs an
air dielectric for low-loss operation past 15 GHz.

Racal Instruments Is Now Aeroflex

Aeroflex announced that it has changed the name of Racal Instruments
Wireless Solutions (RIWS) to Aeroflex. Aeroflex had acquired RIWS, based
in Burnham, England, from Racal Instruments Group Holding on July 31,
2003. According to Len Borow, CEO and Vice Chairman of Aeroflex, "Our
goal is to grow through product sales and acquisitions to become one of
the top test and microelectronics companies in the world. To help
achieve this goal, it is important to have a single Aeroflex brand
recognized worldwide."

Radstone Processors Power Polish F-16s

Radstone Embedded Computing announced that its PowerXtreme PPC7D
single-board computer, PMCGA3 graphics accelerator, and PMCF2
CompactFlash PMC had been selected by Goodrich Corp.'s Surveillance &
Reconnaissance Systems team for inclusion in the Poland Peace Sky F-16
Reconnaissance program. As part of the Foreign Military Sale (FMS),
Goodrich will provide a reconnaissance pod to the Polish Air and Air
Defense Forces. The pod's sensors are capable of imaging targets at
30,000 feet at a standoff distance of 50 nautical miles. The system will
help support NATO forces in Europe.

Full-Wave Simulation Supports Spiral Inductors

Semiconductor foundry United Microelectronics Corp. (UMC) and software
supplier Ansoft have teamed on a parameterized spiral-inductor design
kit based on full-wave three-dimensional simulation. The close linking
of simulation software with foundry allows designers the flexibility to
create new inductor geometries simply by editing parameters, such as
diameter, width, and number of turns, from a dialog box in Ansoft's HFSS
software. According to Dr. Albert Yen, manager of UMC's Mixed-Mode and
Radio Frequency Technology Program, "Our collaboration with Ansoft
allows our customers to design, simulate, and optimize spiral inductors
on silicon substrates, relieving a major bottleneck of the RF CMOS
design flow." The spiral inductor design kit is current available at no
charge to UMC customers.

NEC Sells 200,000th Microwave Link

Since selling its first PASOLINK 18-GHz microwave link system in the
mid-1980's, NEC Corporation has grown steadily, reaching a total number
of sales of 200,000 systems in December 2004. Designed mainly for
telecommunications systems backhaul networks, the systems are now
shipped at operating frequencies from4 to 52 GHz with as much as 155
Mb/s traffic capacity on each of two channels. Used as backups for
optical networks, for WLAN interconnections, and for business and
private networks, the systems have enjoyed recent demand in China,
Russia, and India for expanding network applications.

Note Explores Verification of Load-Pull Systems

Load-pull systems are based on mechanical or solid-state tuners that
provide variable source and load impedances to a device under test
(DUT). Such systems are invaluable when designing an amplifier for
maximum output power or efficiency, for example. But verification of
measurement data can be difficult, and requires repeatable calibration
procedures. Fortunately, a free 11-page application note from Maury
Microwave Corp., "Basic Verifcation of Power Load-Pull Systems," reviews
common sources of errors and how to control them. Copies of the note are
available for free download from the company's website.
