QPB3311
15 dB Return Path Amplifier 5ꢀ–ꢀ210ꢀMHz
®
Product Overview
The QPB3311 is an HBT single ended RF amplifier IC
operating as return path amplifier capable of
supporting DOCSIS 3.1 applications. This IC is
designed to provide a low noise, high gain option for
5-210MHz interface using an 8V power supply to
provide lower overall power dissipation. 5V operation
is possible in applications with reduced linearity and
gain requirements. The QPB3311 is packaged in a
convenient SOIC8 package and features an externally
adjustable bias control.
Package: SOIC-8 with Exposed Pad
