HSP50215 Data Sheet January 1999 File Number 4346.4 Digital UpConverter 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.

The HSP50215 supports both vector
