    Key Features

    • 2.3 - 5.0 GHz Operational Frequency
    • 50Ω Matched RF Input and Output
    • +27 dBm P3dB
    • 36.5 dB Gain at 2.6 GHz
    • +5 V Single Supply, ICQ adjustable
    • DC Power Shutdown Feature

    The QPA9122M is a wideband, high gain and high linearity driver amplifier. It provides 36.5dB gain at 2.6GHz and achieves a peak power of 27dBm P3dB. The amplifier can provide good DPD linearity performance with wideband signals of up to 200 MHz wide 5G NR signals, making it perfectly suited for m-MIMO applications.
    The QPA9122M 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.
    QPA9122M also has external bias control capability for linearity optimization.

    The QPA9122M is housed in a 16-pin 3X3mm SMT package and is footprint and pin-compatible to QPA9120,QPA9121 and QPA9122.
