QPB8896
®
25 dB Balanced Return Path Amplifier (5 – 700 MHz)
Product Overview
The QPB8896 is a GaAs pHEMT RF balanced amplifier IC
operating as return path amplifier capable of supporting
FDx and DOCSIS 3.1 applications. This IC is designed to
provide a low noise, high gain option for 5 – 700 MHz
interface using a 5 V power supply to provide lower overall
power dissipation. QPB8896 is in a convenient SOIC-8
package.
