Analog Devices Inc. introduced a two-chip IF (intermediate frequency) receiver solution that radmatically improves the data bandwidth and capacity of next-generation, multi-carrier wireless base stations compatible with emerging 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 dramatically 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, which improves base station receiver sensitivity and dynamic range and ensures both weak and strong incoming cell phone call signals are quickly and effectively received and processed. 

The AD8376 and AD6655 comprise the first two-chip dual-channel IF receiver optimized to handle both the main and diversity receive paths simultaneously.  The combination of best-in-class performance, power consumption, size and cost is ideally suited to meet the wider bandwidth and multi-carrier signal processing demands of today's wireless infrastructure equipment, while supporting emerging 3G and 2.5G mobile phone communications standards such as CDMA2000, UMTS and TD-SCDMA, as well as WiMAX
