Qorvo QPC7331 Variable Cable Slope Equalizers

Qorvo QPC7331 Variable Cable Slope Equalizers are engineered to compensate frequency‑dependent cable loss in broadband networks. Operating over 5MHz to 834MHz, the Qorvo QPC7331 delivers an inverse cable-loss response with a typical slope range of 1.3dB to 18dB, enabling precise upstream equalization for DOCSIS 3.1/4.0 and CATV amplifier/transmission systems. Built on SOI technology, the QPC7331 combines high linearity (input IP3 up to 50dBm) with low insertion loss (typically 1.7dB at 834MHz) while maintaining 75Ω impedance and low power consumption (3mA typical) in a compact 14‑pin SMT package.
