描述 Description

This device is an ultra-miniature balun. The BALF-SPI2-02D3 integrates matching

network and harmonics filter. Matching impedance has been customized for the ST

S2-LP transceiver. The BALF-SPI2-02D3 uses STMicroelectronics IPD technology on

non-conductive glass substrate which optimize RF performance.
