Introduction

The QPA9219 is a high- linearity two- stage power amplifier in a low- cost surface- mount package with on- chip bias control and temperature compensation circuits. The amplifier provides 30.4 dB gain over the 1930 - 1995 MHz frequency range covering 3GPP Bands 2, 25, 36 without the need of linearization circuitry such as DPD. It is able to achieve - 50 dBc ACLR at +24 dBm output power using 20 MHz LTE signal (9.5 dB PAR). The QPA9219 integrates two high performance amplifier stages onto a module to allow for a compact system design and requires very few external components for operation. The product is bias adjustable allowing the amplifier's power consumption to be optimized and is available in a RoHS- compliant 7×7 mm surface mount package. The QPA9219 is targeted for small cell or enterprise Femtocell basestation applications, distributed antenna systems (DAS), repeaters, and/or booster amplifiers.
