Description
AI
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.
