    Qorvo's QPA9419 is a high-linearity three-stage power amplifier in a low-cost surface-mount package with on-chip bias control and temperature compensation circuits. The amplifier provides 30 dB gain over the 1930-1990 MHz frequency range and can be utilized without the need of linearization circuitry such as DPD. It is able to achieve -48 dBc ACLR at +27 dBm output power using 20 MHz LTE signal (9.5 dB PAR). The QPA9419 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 lead-free/RoHS-compliant 7x7 mm surface mount package.

    The QPA9419 is targeted for small cell or enterprise Femtocell basestation applications, distributed antenna systems (DAS), repeaters, and/or booster amplifiers.
