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".
