Product Overview
The QPB8858 is a GaAs pHEMT/MESFET 75-ohm
push-pull RF amplifier IC featuring over 34dB of flat
gain and low noise. This IC is designed to support
DOCSIS 3.1 applications up to 1218MHz using a
single 24V supply. The QPB8858 offers low noise and
low distortion at high efficiency consuming only 7W in
a 5x7 QFN package. Its compact size and low ϴjc
enable integration that is ideally suited for hybrid
module applications.

Recommended Mounting Pattern
•
•
•
•
Ensure good package backside paddle solder attach for reliable operation and best electrical performance.
Place mounting screws near the part to fasten a back-side heat sink.
Do not apply solder mask to the back side of the PC board in the heat sink contact region.
Ensure that the backside via region makes good physical contact with the heat sink.
