Qorvo QPC7331 Variable Cable Slope Equalizers

Introduction

The Qorvo QPC7331 Variable Cable Slope Equalizers are advanced semiconductor components designed to enhance the performance of broadband networks. By compensating for frequency-dependent cable loss, these equalizers ensure optimal signal quality across a wide operational bandwidth.

Part Description

The QPC7331 operates within a frequency range of 5MHz to 834MHz, providing an inverse cable-loss response with a slope range of 1.3dB to 18dB. This feature is particularly beneficial for applications requiring precise upstream equalization, such as DOCSIS 3.1/4.0 and CATV amplifier/transmission systems. Built on Silicon-On-Insulator (SOI) technology, the QPC7331 boasts high linearity with an input IP3 of up to 50dBm and low insertion loss, typically around 1.7dB at 834MHz. It maintains a 75Ω impedance, ensuring compatibility with CATV applications while consuming minimal power (3mA typical) in a compact 14-pin SMT package.
