QPQ1289

    LTE Extended Band 4 / Band 10 BAW Duplexer

    Key Features

    • Very Small Size (2.00 x 2.50 x 0.91 mm)
    • Low Insertion Loss (2.0 dB, 2.3 dB, typ)
    • High Rejection
    • Steep skirts and low temperature drift provides excellent Wi-Fi rejection

    The QPQ1289 is a high performance Bulk Acoustic Wave (BAW) duplexer, designed for basestation uplink / downlink applications. The device’s low insertion loss and high attenuation make it ideal for small cells.

    The duplexer is designed using BAW filters that provide very steep skirts and low temperature drift, allowing excellent rejection of Wifi and other interfering signals. It is housed in a compact, RoHs-compliant 2.00 mm x 2.50 mm x 0.91 surface mount package (SMP).
