Digital Up/Down Converters

Analog Devices digital up/downconverters serve as the frequency translator and digital filter between data converters and DSP block. These innovative products enable highly programmable and configurable receive and transmit signal chains, allowing multi-channel, multi-carrier radio platforms in 3G wireless base stations. They also meet the digital data conversion requirements for many other communications applications.
