• 50Ω Matched RF Input and Output
• 1 dB Gain Flatness over 1 GHz Bandwidth
• +22 dBm P1dB
• +35 dBm Output IP3
• 29 dB Gain

• Small 3 x 3 mm QFN Package
Product Overview
The QPA9120 is a wideband, high gain, and high linearity
driver amplifier in a low-cost, RoHS compliant 3x3 mm QFN
package. With Qorvo’s E-pHEMT process, this amplifier
delivers exceptional performance with 36 dBm output 3rd
order intercept (OIP3) power and 22 dBm output 1dB
compression (OP1dB) power while consuming less than
100 mA DC current with single 5V supply.
The QPA9120 incorporates on-chip features with fast DC
power shutdown, externally configurable device DC
operation current, and is internally matched.
The QPA9120 is targeted for use as a pre-driver amplifier
for wireless infrastructure where high linearity, medium RF
power with efficient DC power operation are required. The
device is an excellent choice for 5G dense-array m-MIMO
radio applications.

Package Marking and Dimensions
Marking: Pin 1 marker – Dot and Logo – Q
Part Number – 9120
Trace Code – XXXX up to 4 Characters assigned by sub-contractor
Notes:
1. All dimensions are in millimeters. Angles are in degrees.
2. The terminal #1 identifier and terminal numbering conform to JESD 95-1 SPP-012.
3. Contact plating: NiPdAu
Recommended PCB Layout 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. 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 (0.01”).
4. Ensure good package backside paddle solder attach for reliable operation and best electrical performance.
