AD6600: 分集接收机芯片组
ADI公司创新的分集接收机芯片组是一款紧凑的综合解决方案，提供两个中频至基带分集通道，片内集成自动增益控制、接收信号强度指示器、高分辨率数字控制振荡器(NCO)和数字滤波。该芯片组内置ADI公司的双通道中频采样模数转换器AD6600和双通道抽取接收机芯片AD6620。同时配置适当的外部元件，能够处理各种各样的空中接口标准，包括GSM、CDMA、IS136、PHS，以及用于寻呼系统和无线固定接入接收机的专有调制方案。该分集接收机基于ADI公司的新一代接收机架构，用数字滤波器取代了灵敏的模拟滤波器，从而显著降低成本、缩小尺寸。完整的参考设计所展示的最佳布局，不仅可降低噪声，还使跨通道耦合降至最小。
Analog Devices' innovative Diversity Receiver chipset delivers two IF-to-baseband diversity channels in a compact, comprehensive solution that incorporates Automatic Gain Control, Received Signal Strength Indicator, high-resolution Numerically Controlled Oscillator and digital filtering on-chip.
The chipset comprises Analog Devices' AD6600 dual-channel IF sampling analog-to-digital converter and AD6620 dual-channel decimating receiver chip. Configured with the appropriate external components, it can address a variety of air interface standards, including GSM, CDMA, IS136 and PHS, as well as proprietary modulation schemes for paging systems and wireless fixed access receivers.Based on Analog Devices' next-generation receiver architecture, the Diversity Receiver replaces sensitive analog filters with digital filters for significant cost and size reductions. Complete reference designs show the optimal layout for reducing noise and minimizing cross-channel coupling.
