Product Overview
The QPA9908 is a high-efficiency, linearizable power
amplifier targeting Band 8 small-cell wireless infrastructure
systems. The product delivers high efficiency of 36% at
+28dBm average output power, while providing excellent
DPD linearized ACPR of -48dBc for signal bandwidths of
up to 40MHz.
The QPA9908 is housed in a 5x5mm SMT package. It is
pin-to-pin compatible to QPA9903 (band 3 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.
