QPA9940
2300-2400MHz 4 W High-Efficiency Amplifier
®
Product Overview
The QPA9940 is a high-efficiency, linearizable power
amplifier targeting Band 40 small-cell wireless
infrastructure
systems. Using
InGaP/GaAs
HBT
technology, the product delivers high efficiency of 31% at
+28dBm average output power while providing excellent
DPD linearized ACPR of -50 dBc for signal bandwidths of
up to 100MHz.
16 Pad 5ꢀxꢀ5ꢀmm Package
The QPA9940 is housed in a 5x5mm SMT package. It is
pin-to-pin compatible to QPA9901, QPA9903 and
QPA9908 (high-efficiency small cell PA).

Notes:
1. All dimensions are in millimeters. Angles are in degrees.
2. Use 1 oz. copper minimum for top and bottom layer metal.
3. Via holes 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.

Tape and Reel Information – Reel Dimensions
Packaging reels are used to prevent damage to devices during shipping and storage, loaded carrier tape is typically wound onto a
plastic take-up reel. The reel size is 13" diameter. The reels are made from high-impact injection-molded polystyrene (HIPS), which
offers mechanical and ESD protection to packaged devices.
