The Complex Digital Up Converter (DUC) developed by Zipcores is specialized for converting baseband signals into intermediate frequency (IF) signals with remarkable accuracy. This 16-bit complex digital up-converter is equipped with an interpolation filter that is fully configurable, optimizing the process of increasing the sample rate for the transmission. Featuring a sophisticated digital oscillator and well-optimized filter architecture, the DUC seamlessly integrates into systems requiring efficient baseband to IF conversion, enabling precise modulation of the signal for transmission across different media. It is especially beneficial in applications that demand high-quality signal conversion with an emphasis on maintaining signal fidelity and performance throughout the conversion process.
