    Key Features

    • Fully integrated 2-stage PA
    • Internally matched to 50 Ohms
    • -50dBc ACLR at Pavg = 27dBm
    • 30.5dB Gain
    • 14.6% PAE at 27dBm
    • On-chip control bias and temperature compensation circuit

    The QPA9418 is a high-linearity two-stage power amplifier in a low-cost surface-mount package with on-chip bias control and temperature control circuits, suitable for small cell base station applications. The QPA9418 provides 30.5 dB gain and +27 dBm linear power over the 1.805 – 1.880 GHz frequency range. This amplifier is able to achieve −50 dBc ACLR at +27 dBm output power using 20 MHz LTE signal. The QPA9418 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 amplifier is bias adjustable allowing the amplifier’s power consumption to be optimized. The QPA9418 is available in a 7 x 7 mm surface mount package.
