General Description
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 +44 dBm OIP3 and
+27.2 dBm P1dB while only consuming 130 mA quiescent
current. All devices are 100% RF and DC tested.
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.
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.
