Sterling-LWB

The LSR Sterling-LWB Module is available in three different versions. Depending on the user’s antenna and
footprint needs, there is a variant to suite most application requirements. LSR recommends that for simplicity of
both the host PCB design, as well as the manufacturing process, that either the Chip Antenna or RF Connector
version of the modules be used in your design.

    DESCRIPTION
    The Sterling-LWB is a high performance 2.4 GHz
    WLAN and Bluetooth combo module based on
    latest-generation silicon (Broadcom’s BCM4343W).
    With an industrial temperature rating, broad
    country certifications, and the availability of three
    different package styles, the Sterling-LWB provides
    significant flexibility to meet various end user
    application needs.
    The on-module chip antenna package style for the
    Sterling-LWB eliminates complexity for design
    integration, simplifies manufacturing assembly with
    larger pin outs, and features an advanced chip
    antenna that offers greater resistance to de-tuning
    than typical trace or chip antennas.
    The module includes the MAC, Baseband and Radio
    to support WLAN applications and an independent,
    high-speed UART is provided for the Bluetooth host
    interface. In addition, the latest Linux and Android
    drivers are supported directly by LSR and
    Broadcom.
