Taking Performance To a New Peak - 4500B

Boonton introduces the new 4500B Peak Power Analyzer which has been
totally redesigned from the inside out. This meter is changing the
way the industry views and analyzes RF data. Some of the key
features include: 8.4" TFT color LCD display, 100 ps timebase
resolution, automatic peak-to-peak, delay-by-time and
delay-by-events triggering, and many more.

How Much Wireless Is Enough?

Most people, engineers or not, have experienced the frustration of a
cellular phone call gone bad: a dropped call because of poor cell
coverage, excessive distortion due to multipath or interference, and
so on. Regular cellular users chalk it up as "part of the
experience." The promise of 3G (and then 4G), of course, is better
performance. That is all well and good, except for one thing: the
growth of wireless implies the steady increase of interferers and
"wireless weak links" in a communications network.

As an example, a friend called the other day from his car using a
mobile phone. Military vets would have been proud of the scrambling
code that this call represented, with about one of every four words
getting through. Unfortunately, it wasn't meant to be a coded call.
When my friend finally got through clearly, I asked what
modifications he had made. His answer was to disconnect the
Bluetooth headset and go directly to the phone. So, here was a case
where two wireless devices didn't necessarily add up to better
performance. And, in the future, we only have to look forward to
more and more wireless devices interacting: a failure anywhere along
a signal chain breaks the chain. How much wireless is enough? I

Fujitsu Introduces 65-nm ASIC Processes

Fujitsu Microelectronics America (Sunnyvale, CA) unveiled its
world-class 65-nm (gate-length) CS200 and CS200A processes this week
for ASIC customers. The former process is aimed at microprocessor
design while the latter is geared for mobile communications
applications. These advanced processes promise longer battery life
and lower power consumption than the firm's earlier 90-nm processes,
due to the smaller size of the transistors (only 30 nm long). Both
are core 1-V processes designed to maximize battery life in fixed
and mobile applications.

AWR Teams With Nuhertz For Filter Synthesis

Software supplier Applied Wave Research (AWR, El Segundo, CA)
announced a new integrated filter synthesis solution using Nuhertz
Technologies' (Phoenix, AZ) filter synthesis technology. The
software solution is now available in AWR's Microwave Office and
Analog Office design suites. High-frequency circuit designers can
now perform accurate filter synthesis quickly and easily from within
the unified AWR design platform. According to James Spoto, President
and CEO of AWR, "Nuhertz offers exceptional technology in the area
of filter synthesis and has demonstrated the same commitment to
quality and feature enhancement that has been an AWR tradition." The
AWR/Nuhertz filter synthesis solution offers complete synthesis
capability for passive, transmission line, active, switched
capacitor, and digital filters. The solution offers two graphical
user interfaces (GUIs), one for the power user who requires advanced
options and capabilities, and one for the mainstream user who needs
ease of use.

Alvarion Selects Freescale Processors For WiMAX BS

Broadband wireless access (BWA) equipment supplier Alvarion (Tel
Aviv, Israel) has selected the most powerful of Freescale
Semiconductor's PowerQUICC III baseband processors for its WiMAX
base-station (BS) design for both fixed and mobile broadband
wireless connectivity. According to David Perkins, senior vice
president and general manager of Freescale's Networking and
Computing Systems Group, "WiMAX technology provides a compelling
platform for fixed systems and seamless mobility in the broadband
wireless access market, and we applaud Alvarion's innovation and
leadership in this emerging market." WiMAX technology, which is
based on the IEEE 802.16 air interface standard and the ETSI
HiperMAN wireless metropolitan area network (MAN) standard, has been
developed to provide high-bandwidth wireless services such as voice,
data, and multimedia.

New Connector Goes On Easy

Times Microwave Systems (Wallingford, CT), a division of Smiths
Group, has developed a solderless two-piece clamp-style connector
for its LMR-600 low-loss cables. The connector has a combination
hex/knurl coupling nut that allows tightening by hand or with a
wrench. The EZ-600-NMC02 connector is suitable for applications
through 5.8 GHz and is designed specifically for the LMR flexible
cables, which are used for standard interconnects, antenna feeders,
and system jumpers.

CEL Offers Optocoupler Guidelines

California Eastern Laboratories (CEL) has completed a new brochure
for designers who employ high-speed digital and analog optocouplers
as isolation devices. The brochure characterizes the isolation
requirements for a variety of applications including RS422, RS485,
CAN and USB interfaces, motor drive control and power supply
isolation, as well as isolation for 802.3af Power over Ethernet. The
literature includes key specifications for all of CEL/NEC's
high-speed optocouplers.

National Expands PXI Switch Line To 26.5 GHz

National Instruments (Austin, TX) had added four microwave switch
modules based on the PXI format. The new units include multiplexers,
single-pole, double-throw (SPDT) relays, and transfer switch modules
for routing signals through 26.5 GHz in automated-test-equipment
(ATE) systems. Based on relays from Radiall, the modules feature
less than 1 dB insertion loss through 26.5 GHz. The company has also
announced the latest version of its NI Switch Executive switch
management software for remote control of and ease of configuring
the new modules.
