Analog Devices introduced a two-chip IF (intermediate frequency) receiver to address the data bandwidth and capacity of next-generation, multi-carrier wireless base stations compatible with emerging 3G cellular transmission standards. The dual-channel AD8376 VGA (variable gain amplifier) and AD6655 IF diversity receiver replace 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, according to the company, 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 two-chip dual-channel IF receiver optimized to handle both the main and diversity receive paths simultaneously.
