BAL-2690D3U:50Ω / 30+j25 balun transformer for 2.45 GHz ISM band

The BAL-2690D3U 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 0.8 dB insertion losses in the bandwidth(2400 MHz - 2500 MHz) 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 performance.

Key Features

  • 50 Ω nominal input / 30+j25 output differential impedance
  • Low insertion loss
  • Low amplitude imbalance
  • Low phase imbalance
  • Small footprint: BAL-2690D3U < 1 mm²
