BAL-2690D3U

50 / 30+j25 Balun transformer for 2.45 GHz ISM band
  • active Active

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.
