50 – 1003 MHz CATV Doubler Amplifier: QPB8957

Qorvo offers the QPB8957 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 1003 MHz using a single 24V supply.

The QPB8957 offers low noise and low distortion at high efficiency consuming only 8.4W 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, and for use in head end CMTS equipment and 75-ohm amplifiers.

Additional QPB8957 features include:

  • High Gain: 28dB @ 1003MHz
  • Adjustable Bias
  • 50 - 1003 MHz BW
  • 56dBmV/ch virtual 1.0GHz, at 15dB tilt
  • Low Noise: 4.5dB
  • Excellent Composite Distortion
