Qorvo QPB8808 Amplifier Multi-Chip Module
Qorvo QPB8808 Amplifier Multi-Chip Module (MCM) is an ultra-linear, QFN GaAs amplifier module designed for output-stage amplification in CATV infrastructure applications. Qorvo QPB8808 MCM is designed to provide cable broadband service providers an easy upgrade path to DOCSIS 3.1 with maximum flexibility and functionality while conserving power and reducing board space.
The QPB8808 Module features a push-pull cascode design which provides flat gain along with ultra-low distortion, ideal for use in CATV distribution systems requiring high output power capability.
The QPB8808 draws approximately 525mA from a single +12V supply. This module operates from 45MHz to 1218MHz, offers 20.6dB gain (typical) and +58dBmv power output. The QPB8808 model also includes a variable current bias adjust feature to conserve power while maintaining high output.
The QPB8808 is packaged in an industry standard 40-pin 5mm x 7mm QFN package with exposed paddle (EP) beneath the device for thermal and electrical grounding. The compact multi-chip design of this module provides a cost effective solution, saving board space compared to traditional hybrid packages.
