AD6636BBCZ

PRODUCT DESCRIPTION

The AD6636 is a digital down-converter intended for IF sampling or oversampled baseband radios requiring widebandwidth input signals. Optimized for the demanding filtering requirements of wideband standards, such as CDMA2000, UMTS, and TD-SCDMA, the AD6636 is designed for radio systems that use either an IF sampling ADC or a baseband sampling ADC.
