Analog Devices Inc. introduced its integrated IF-to-baseband diversity receiver for GSM/EDGE wireless base stations. Combining the functionality of seven components on a single chip, this new receiver enables base station designers to meet strict EDGE performance requirements at 50 percent of the cost of existing solutions, the company says.

The AD6650 replaces five active components and two SAW filters in existing solutions, reducing both board size and test costs, the company says. An on-chip synthesizer with an integrated VCO drives the I&Q demodulator. The AD6650 can accommodate IF input frequencies from 70 MHz to 300 MHz, and features a linear signal range of more than 106 dB and a dynamic range of more than 110 dB. The AD6650 is sampling now and will be in full production in the fall of 2003. It is available in 121-pin plastic ball-grid array (BGA) packaging priced at $20.00 per unit in 1,000-piece quantities.
