STMICROELECTRONICS BALFSPI02D3 Impedance Matched Balun Filter
The STMicroelectronics BALF-SPI-02D3 is an ultra-miniature balun designed for use with the SPIRIT1 transceiver. This component integrates a matching network and harmonics filter, utilizing STMicroelectronics' IPD technology on a non-conductive glass substrate to optimize RF performance. The BALF-SPI-02D3 offers a very low profile, reducing the RF bill of materials (BOM) and area requirements in applications such as 434 MHz impedance-matched balun filters. Its features include low insertion loss, low amplitude imbalance, and low phase imbalance, making it ideal for space-constrained applications requiring high RF performance.
