3.1 - 4.2 GHz Single Channel Switch-LNA

    Key Features

    • 3.1 - 4.2 GHz Operating Range
    • 35.5 dB Gain
    • 1.2 dB NF
    • 38.5 dBm max Input Power in Tx Mode

    The QPB9362 is a highly integrated front-end module targeted for 5G TDD systems. The switch LNA module integrates an LNA with a high-power handling switch which can be used as a failsafe path to termination when radio is in transmitting mode. LNA Power down mode is available via T/R control pin on the module. The QPB9362 provides 34.5 dB of gain with 1.1 dB typical noise figure over the entire operating frequency band in the receiving mode.

    The QPB9362 is packaged in a RoHS-compliant, compact 5 mm x 3 mm LGA package. The switch LNA module is targeted for 5G wireless infrastructure applications configured for TDD-based mMIMO architectures.
