Wideband Programmable Modulator (WPM)
The HSP50415 Wideband Programmable Modulator (WPM) is a quadrature amplitude modulator/upconverter designed for wideband digital modulation. The WPM bines shaping and interpolation filters, a plex modulator, timing and carrier NCOs and dual DACs into a single package. The HSP50415 supports vector modulation, accepting up to 16-bit In phase (I) and Quadrature (Q) samples to generate virtually any quadrature AM or PM modulation format. A constellation mapper and 24 Symbol span interpolation shaping filter is provided for the input baseband signals. Gain adjustment is provided after the...
