HSP50215 Overview
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 bines shaping and interpolation filters, a plex modulator, and Timing and Carrier NCO’s into a single package. Each DUC can create a single FDM channel.
