QPA9418

High Linearity 0.5 W Small Cell PA

Product Overview

The QPA9418 is a high-linearity two-stage power amplifier

in a low-cost surface-mount package with on-chip bias

control and temperature control circuits, suitable for small

cell base station applications.

The QPA9418 provides 30.6ꢁdB gain and +27ꢁdBm linear

power over the 1805ꢁ–ꢁ1930ꢁMHz frequency range. This

amplifier is able to achieve −48ꢁdBc ACLR at +27ꢁdBm

output power using 20 MHz LTE signal.

7ꢀmmꢀxꢀ7ꢀmm Leadless SMT Package

The QPA9418 integrates two high performance amplifier

stages onto a module to allow for a compact system design

and requires very few external components for operation.

The amplifier is bias adjustable allowing the amplifier’s

power consumption to be optimized. The QPA9418 is

available in a 7ꢁxꢁ7ꢁmm surface mount package.
