  • STMicroelectronics BALF-NRF01E3 is an ultraminiature balun. The BALF-NRF01E3 integrates matching network in a monolithic glass substrate. Matching impedance has been customized for the nRF51822-QFAA/AB/AC and nRF51422-QFAA/AB/AC RF transceivers.

    It uses STMicroelectronics IPD technology on non-conductive glass substrate which optimizes RF performance.

    Key Features

    • Low insertion loss
    • Low amplitude imbalance
    • Low phase imbalance
    • Coated CSP on glass
    • Small footprint: < 1.5 mm2
    • Benefits
      • Very low profile
      • High RF performance
      • PCB space saving versus discrete solution
      • BOM count reduction
      • Efficient manufacturability
