STMicroelectronics BAL-NRF01D3/NRF02D3 50 Ohm Balun Transformer

STMicroelectronics BAL-NRF01D3/NRF02D3
50 Ohm Balun Transformer

STMicroelectronics BAL-NRF01D3/NRF02D3 50 Ohm Balun Transformer is an ultra miniature balun. They both integrate a matching network and harmonics filter. Matching impedance has been customized for the following Nordic Semiconductor circuits: nRF24LE1 QFN-32 pins, nRF24AP2-1CH, nRF24AP2-8CH, nRF51422, nRF51822, nRF51422-CEAA and nRF51822-CEAA. They use STMicroelectronics IPD technology on non-conductive glass substrate which optimize RF performances. These Balun Transformers have been tested and approved by Nordic Semiconductor in their nRFgo modules..

Features
  • 50Ω nominal input / conjugate match to Nordic Semiconductor chips nRF24LE1 QFN32, nRF24AP2-1CH, nRF24AP2-8CH, nRF51422 and nRF51822
  • Low insertion loss
  • Low amplitude imbalance
  • Low phase imbalance
  • Small footprint:
    • < 1.5 mm2 (BAL-NRF01D3)
    • < 1.2 mm2 (BAL-NRF02D3)
  • Very low profile:
    • < 595 μm after reflow (BAL-NRF01D3)
    • < 560 μm after reflow (BAL-NRF02D3)

  • High RF performance
  • RF BOM and area reduction

Applications
  • 2.45 GHz impedance matched balun filter
  • Optimized for Nordic's chip set nRF24LE1/AP2, nRF51, nRF51422-CEAA, and nRF51822-CEAA series
