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

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.
