BALF-SPI2-01D3   Product is in volume production.

50 Ω nominal input / conjugate match balun to S2-LP,868 - 927 MHz with integrated harmonic filter

Download Datasheet

This device is an ultra-miniature balun. The BALF-SPI2-01D3 integrates matching network and harmonics filter. Matching impedance has been customized for the ST S2-LP transceiver. The BALF-SPI2-01D3 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 860 - 930 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
