General Description
The QPA9226 is a high-linearity three-stage power
amplifier in a low-cost surface-mount package with on-chip
bias control and temperature control circuits, suitable for
small cell or enterprise Femto cell base station applications.
The QPA9226 provides 34 dB high gain and −47 dBc ACLR
at +24 dBm linear power using a 20 MHz LTE signal over
the 2.5 – 2.7 GHz frequency range covering 3GPP Bands
7, 38, 41.
The QPA9226 integrates three high performance amplifier
stages 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 for specific performance
requirements. The QPA9226 is available in a lead-
free/RoHS-compliant 7 x 7 mm surface mount package.

PCB Mounting Pattern
Notes:
1. All dimensions are in millimeters. Angles are in degrees.
2. Use 1 oz. copper minimum for top and bottom layer metal.
3. Vias are required under the backside paddle of this device for proper RF/DC grounding and thermal dissipation. We recommend a 0.35mm
(#80/.0135") diameter bit for drilling via holes and a final plated thru diameter of 0.25 mm (0.10”).
4. Ensure good package backside paddle solder attach for reliable operation and best electrical performance.
