STMicroelectronics BAL-2690D3U Balun Transformer

STMicroelectronics BAL-2690D3U Balun Transformer is a balun designed to transform single ended signals to differential signals in Bluetooth applications. The BAL-2690D3U has been customized for the STLC2690 Bluetooth transceiver with 0.8dB insertion losses in the bandwidth (2400MHz - 2500MHz) and with a specific requirement for the SCC22 parameter. The BAL-2690D3U has been designed using STMicroelectronics IPD (integrated passive device) technology on non conductive glass substrate to optimize RF performances.

Features
  • 50Ω nominal input / 30+j25 output differential impedance
  • Low insertion loss
  • Low amplitude imbalance
  • Low phase imbalance
  • Small footprint: BAL-2690D3U < 1mm²
  • Very low profile (<700μm)
  • High RF performances
  • RF BOM and area reduction
Applications
  • Balun transformer for applications such as:
  • Bluetooth STLC2690
  • Mobile phone
