AD6640 多通道、多模式接收机芯片组

AD6640: 多通道、多模式接收机芯片组

利用ADI公司突破性的数字无线电接收机设计，您可以稳操胜券地将可编程宽带无线电基站推向市场。这款先进的“软件”接收机基于ADI公司功能丰富的高性能芯片AD6640和AD6620。AD6640是一款宽带模数转换器，能够以65 MSPS的速率进行采样。AD6620是一款65 MSPS抽取接收机芯片，支持将同一无线电调谐到不同的信道，甚至支持不同的空中接口标准。AD6640采用业界领先的高动态范围宽带采样技术，能够一次性完成整个25 MHz频谱的数字化。因此，一个全数字宽带无线电就能取代多个模拟无线电，最终解决方案将更小、更灵活、更便于配置，有助于客户避免网络规划的不确定性。

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 AD620 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.
