Upconverter

Definition

An upconverter is a device which provides frequency conversion to a higher frequency, e.g., in digital broadcast-satellite applications.

DUCs and QDUCs

Digital upconverters (DUCs), and quadrature digital upconverters (QDUCs), serve as the frequency translator and digital filter between data converters and DSP blocks.

DUCs enable highly programmable and configurable receive and transmit signal chains, allowing multichannel, multicarrier radio platforms in 3G wireless base stations. They also meet the digital data conversion requirements for many other communications applications.
