Applications

  • DOCSIS 3.1
  • Broadband CATV hybrid modules
  • Head End CMTS Equipment
  • 75-ohm amplifiers Product Overview The QPB8857 is a GaAs pHEMT/MESFET 75-ohm Doubler RF amplifier IC featuring over 28dB of flat gain and low noise. This IC is designed to support DOCSIS 3.1 applications up to 1218MHz using a single 24V supply. The QPB8857 offers low noise and low distortion at high efficiency consuming only 10.5W in a 5x7 QFN package. Its compact size and low ϴjc enable integration that is ideally suited for hybrid module or an alternative to hybrid module applications.
