AD6636BC中文资料亚德诺数据手册PDF规格书

GENERAL DESCRIPTION

The AD6636 is a digital downconverter intended for IF sampling or oversampled baseband radios requiring wide bandwidth input signals. The AD6636 has been optimized for the demanding filtering requirements of wideband standards, such as CDMA2000, UMTS, and TD-SCDMA, but is flexible enough to support wider standards such as WiMAX. The AD6636 is designed for radio systems that use either an IF sampling ADC or a baseband sampling ADC.
