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. Multiple DUC’s can be cascaded digitally for multi-channel applications. The HSP50215 supports both vector and FM modulation. In vector modulation mode, the DUC accepts 16-bit I and Q samples to generate virtually any quadrature AM or PM modulation format. The DUC also has two FM modulation modes. In...
