QPA9119

½ W High Linearity Amplifier

Product Overview

The QPA9119 is a high linearity driver amplifier in a low-

cost, RoHS compliant, surface mount package. This

InGaP/GaAs HBT delivers high performance across a

broad range of frequencies with +44ꢁdBm OIP3 and

+27.2ꢁdBm P1dB while only consuming 130ꢁmA quiescent

current. All devices are 100% RF and DC tested.

16 Pad 3ꢀxꢀ3ꢀmm QFN Package

The QPA9119 incorporates on-chip features that

differentiate it from other products in the market. The

amplifier integrates an on-chip DC over-voltage and RF

over-drive protection. This protects the amplifier from

electrical DC voltage surges and high input RF input power

levels that may occur in a system. On-chip ESD protection

allows the amplifier to have a very robust Class 1C HBM

ESD rating.

Key Features

• 400ꢁ–ꢁ4200ꢁMHz

• +27.2 dBm P1dB

• +44ꢁdBm Output IP3

• 17ꢁdB Gain at 2140ꢁMHz

• +5ꢁV Single Supply, I_CQ=130ꢁmA

• Internal RF Overdrive Protection

• Internal DC Overvoltage Protection

• On Chip ESD Protection

• 3ꢁxꢁ3ꢁmm QFN Package

The QPA9119 is targeted for use as a driver amplifier in

wireless infrastructure where high linearity, medium power,

and high efficiency are required. The device an excellent

candidate for transceiver line cards in current and next

generation multi-carrier 3G / 4G base stations.
