AD6640:  Multi-Channel, Multi-Mode Receiver Chipset

Product Details


Analog Devices' breakthrough design for digital radio receivers lets you bring programmable wideband radio base stations to market with complete confidence.

This advanced 'software' receiver is based on Analog Devices' function-rich, high-performance AD6640 and AD6620 chips. The AD6640 is a wideband analog-to-digital converter capable of sampling at 65 MSPS. The AD6620 is a 65 MSPS decimating receiver chip that enables the same radio to be tuned to different channels and even different air interface standards. Industry-leading high dynamic range wideband sampling enables the AD6640 to digitize an entire 25 MHz of spectrum at one time.

The result: A single all-digital wideband radio replaces multiple analog radios for a smaller, more flexible, more readily configurable solution that helps your customers remove the uncertainty from network planning.
