  • This device is an ultra-miniature balun. The BALF-SPI2-02D3 integrates matching network and harmonics filter. Matching impedance has been customized for the ST S2-LP transceiver. The BALF-SPI2-02D3 uses STMicroelectronics IPD technology on non-conductive glass substrate which optimize RF performance.

    Key Features

    • 50 Ω nominal input / conjugate matched to ST S2-LP for 433 MHz frequency operation
    • Low insertion loss
    • Low amplitude imbalance
    • Low phase imbalance
    • Small footprint
    • Very low profile < 620 μm after reflow
    • High RF performance
    • RF BOM and area reduction
    • ECOPACK®2 compliant component
