QPA9121

    High Gain, 0.5 Watt Driver Amplifier

    Key Features

    • 2.3 – 5.0 GHz Operational Frequency
    • 50Ω Matched RF Input and Output
    • +27 dBm P3dB
    • 28 dB Gain at 2.6 GHz
    • +5 V Single Supply, ICC 95 mA
    • DC Power Shutdown Feature

    The QPA9121 is a wideband, high gain, and high peak power driver amplifier. With Qorvo's GaAs HBT process, this amplifier provides 27dBm P3dB with 28dB gain at 2.6GHz. With a quiescent current of 95mA the part is well suited as a driver in a Tx path DPD loop, for m-MIMO applications.

    The QPA9121 is internally match to 50Ω over the entire operating frequency band of 2.3-5.0 GHz and incorporates a shut-down function through the VPD pin. The amplifier has been proven to provide excellent DPD correction with 5G signals as wide as 160MHz.

    The QPA9121 is housed in a 16-pin 3X3mm SMT package and is footprint and pin-compatible to QPA9120.
