Easing Wireless Base Station Design Complexity
Analog Devices Inc. has introduced a two-chip IF (intermediate frequency)
receiver solution for cellular base stations, pre-configured to support emerging
3G standards. It is expected to improve the data bandwidth and capacity of
next-generation, multi-carrier wireless base stations compatible with 3G
cellular transmission standards. Analog devices' dual-channel AD8376 VGA
(variable gain amplifier) and AD6655 IF diversity receiver solution replaces 48
discrete components, enabling 3G micro- and pico-cell base stations with reduced
power consumption and physical volume. Each radio channel can handle up to six
carriers. The new VGA and IF diversity receiver also increase automatic
gain-control loop performance by 100 times existing options.
The AD8376 dual-channel digitally controlled VGA is sampling now
with full production scheduled for June 2007. The AD8376 is priced at $6.49 per
unit in 1,000-piece quantities and is housed in a 32-lead LFCSP (lead-frame
chip-scale package). A single-channel version, the AD8375, is sampling now with
full production also scheduled for June 2007. The AD8375 is priced at $4.49 per
unit in 1,000-piece quantities and is housed in a 24-lead LFCSP. The AD6653/5 IF
diversity receivers are sampling now with full production scheduled for June
2007. The 12-bit version, the AD6653, is priced at $57.97 and the 14-bit at
$97.50, both in 1,000-piece quantities.
According to Peter Real, product line director, RF and
Networking Components, Analog Devices, "As the industry migrates from
voice-centric services and embraces feature-rich, multimedia content, wireless
infrastructure designers need devices that support the higher data bandwidths
within the next-generation of mobile communications platforms".

Linksys Wireless-N Gigabit Router with Storage Link
Linksys has announced the availability of its first gigabit wireless-N router,
the Wireless-N Gigabit Router with Storage Link (WRT350N). When teamed with the
Wireless-N Notebook Adapter (WPC300N) or Wireless-N Desktop Adapter (WMP300N)
the WRT350N is designed to provide up to four times the range and 12 times the
throughput of standard Wireless-G solutions. The Linksys Wireless-N Gigabit
Router (WRT250N) is available through in India for an estimated street price of
Rs 10,900.
With Storage Link, any USB 2.0 storage device including
inexpensive external USB hard disk drives can become networked attached storage
by simply plugging it into the WRT350N.
In terms of security, wireless transmissions made using the
WRT350N can be encoded with industrial-strength encryption to help protect data
and privacy. It can serve as a DHCP server, supports VPN pass-through, and has a
powerful SPI firewall to help protect against intruders and most known Internet
attacks. Enabling these security features is easy with the Linksys Web
browser-based configuration utility.
