The HSP50215 Digital UpConverter (DUC) is a QASK/FM modulator/FDM upconverter designed for high dynamic range applications such as cellular basestations. The DUC combines shaping and interpolation filters, a complex modulator, and Timing and Carrier NCO’s into a single package. Each DUC can create a single FDM channel. Multiple DUC’s can be cascaded digitally for multi-channel applications.
