Product Overview
The QPA9424 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 base station applications.
The QPA9424 provides 35.8ꢁdB gain and +27ꢁdBm linear
power over the 2300ꢁ–ꢁ2400ꢁMHz frequency range covering
band 30 and band 40. This amplifier is able to achieve
−48.5ꢁdBc ACLR at +27ꢁdBm output power with 20 MHz
LTE signal.
7ꢀmmꢀxꢀ7ꢀmm Leadless SMT Package
The QPA9424 integrates three 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 QPA9424 is
available in a 7ꢁxꢁ7ꢁmm surface mount package.

Notes:
1. Vcc1 draws very little current and provides the bias voltage to the current mirror circuit along with Vref to set the bias point for the whole amplifier.
2. Control signal applied to Vref Pin, 0 to 2.85V
3. Guaranteed by design, not tested in production

Mechanical Information
Package Marking and Dimensions
Marking: Part number – QPA9424
Trace code – Assigned by sub-contractor
Notes:
1. All dimensions are in millimeters. Angles are in degrees.
2. Dimension and tolerance formats conform to ASME Y14.4M-1994.
3. The terminal #1 identifier and terminal numbering conform to JESD 95-1 SPP-012.
PCB Mounting Pattern
Notes:
1. A heat sink underneath the area of the PCB for the mounted device is strictly required for proper thermal operation. Damage to the device can
occur without the use of one.
2. Ground / thermal via holes are critical for the proper performance of this device. Via holes should use a .35mm (#80 / .0135”) diameter drill and
have a final plated thru diameter of .25 mm (.010”).
3. Add as much copper as possible to inner and outer layers near the part to ensure optimal thermal performance.
