QPA9121

High Gain, 0.5 W Driver Amplifier

Product Overview

The QPA9121 is a wideband, high gain, and high peak

power driver amplifier. With Qorvo’s GaAs HBT process,

this amplifier provides 27dBm P3dB with 28dB gain at

2.6GHz. With a quiescent current of 95mA the part is well

suited as a driver in a Tx path DPD loop, for m-MIMO

applications.

16 Pad 3ꢀxꢀ3ꢀmm Laminate Package

The QPA9121 is internally match to 50Ω over the entire

operating frequency band of 2.3-5.0 GHz and incorporates

a shut-down function through the V_PDpin. The amplifier has

been proven to provide excellent DPD correction with 5G

signals as wide as 160MHz.

Key Features

• 2.3ꢁ–ꢁ5.0 GHz Operational Frequency

• 50Ω Matched RF Input and Output

• +27 dBm P3dB

The QPA9121 is housed in a 16-pin 3X3mm SMT package

and is footprint and pin-compatible to QPA9120.

• 28ꢁdB Gain at 2.6 GHz

• +5ꢁV Single Supply, I_CC95ꢁmA

• DC Power Shutdown Feature
