The Bigger The Better? Or Do Good Conferences
Come In Small Packages? By Louis Frenzel, Communications/Test Editor
The wireless industry, especially the cell phone sector, changes so
fast that if you don’t continuously monitor changes, you will
invariably be left in the dust. Conferences are a great way to stay
abreast, but the effectiveness varies from gala to gala.
Network Processor Simplifies ZigBee
Design By Louis Frenzel, Communications/Test Editor
The ZigBee short-range wireless networking technology adds a complex
stack to the IEEE 802.15.4 wireless standard, making it a bear to work
with—especially for designers who aren’t so wirelessly inclined. But
if you want to do mesh networking, it’s the way to go. Just be
prepared for a steep learning curve and a compliance process that takes
both time and money.

Aftermarket battery packs are available for most portable devices.
This webcast, hosted by Electronic Design's Analog/Power Editor Don
Tuite, and sponsored by Micro Power and Panasonic, presents the results
of several product tear-downs on aftermarket battery packs, explains how
substandard aftermarket packs can cut corners on cost, safety
mechanisms, and battery performance, and provides solutions for OEMs to
manage and control their ecosystem of aftermarket battery pack
suppliers.
There was a ton of announcements at the Embedded Systems Conference last
month. Check out the highlights, exclusive commentary, and footage from
the show by Electronic Design's Editor-in-Chief Joe Desposito on our Web
page, sponsored by Lantronix, Xilinx, and Altium. You can also find
video interviews by Electronic Design Europe's Editor-in-Chief Paul
Whytock here.
The applications of robotic arms are expanding. Newly designed LWA
3, a lightweight modular robotic arm from Schunk Intek Inc., is
versatile and covers various areas in robotics including inspection
systems, service robotics, workstations and work processes with
human-machine interaction, mobile platforms (such as light transport,
monitoring and maintenance robots), and tactile, sensor, or camera-based
inspection systems. Check out the specs of this new technology.

Unique Architecture Revamps Power Transistor
Design
Claiming position as the first major advance in silicon RF power
transistor design in more than 15 years, the company's design
architecture reportedly delivers frequency bandwidth, voltage and power
levels that exceed the capabilities of current bipolar and LDMOS
technologies.
The MAX2839, reportedly the industry's first single-chip, 2.3- to
2.7-GHz, WiMAX MIMO RF transceiver in high-volume production, relies on
a dual-receiver architecture to mitigate RF channel fading, thereby
increasing SNR by as much as 10 dB when compared to a single-receiver
architecture.
Groomed specifically for use in 3G dual-band handsets for EGSM
network deployments worldwide, particularly Europe, the AWT6224
dual-band HELP3 power amplifier module supports both IMT (UMTS2100) and
EGSM (UMTS900) bands and meets requirements for WCDMA and HSPA operation
with Qualcomm’s chipsets.
Raising the density bar, the Model 7151 software radio PMC combines
four 200-MHz, 16-bit ADCs that feed a proprietary FPGA IP core with 256
channels of digital down conversion (DDC). With independent frequency
tuning for each DDC channel, the PMC down converts any signal within any
of four digitized, 100-MHz input bands.
Ready for service in applications such as digital radio equipment,
fixed wireless access, satellite communications, and base stations the
CVCO55CC-0827-0840 voltage-controlled oscillator operates from 827 MHz
to 840 MHz with a control voltage range of 0.2 V to 4.7 V.
