QPC7331 5 MHz to 834 MHz Variable Cable Slope Equalizer

Qorvo voltage-controlled equalizers are ideal for DOCSIS upstream applications

Image of Qorvo QPC7331 5 MHz to 834 MHz Variable Cable Slope Equalizer The Qorvo QPC7331 is a voltage-controlled variable slope equalizer designed for cable loss compensation in broadband networks. Operating from 5 MHz to 834 MHz, it provides an inverse cable loss response with adjustable slope control, making it ideal for DOCSIS 3.1 and 4.0 upstream paths. Built on SOI technology, the device offers high linearity and low insertion loss while maintaining a 75 Ω impedance for CATV systems. Its compact 14-pin SMT package and low power consumption simplify integration into amplifier and transmission designs.

Features
  • Operational bandwidth: 5 MHz to 834 MHz
  • Slope range: 2 dB to 18 dB for cable loss compensation
  • Low insertion loss: typically 1.7 dB to 2.5 dB at 834 MHz
  • High linearity: input IP3 up to 50 dBm
  • Single supply: +5 V operation, low current draw ~3 mA
Applications
  • CATV amplifier and transmission systems
  • DOCSIS 3.1 and DOCSIS 4.0 upstream equalization
  • Broadband access network infrastructure
  • Cable TV headend and distribution equipment
  • Evaluation and development using QPC7331PCBA-410 board
