ST’s ultra-miniature BALF-SPI2-02D3 is a balun with Rx and Tx impedances optimized for S2-LP RF transceiver at 433 MHz. The BALF-SPI2-02D3 single-component solution simplifies RF complexity implementation and provides an optimized Rx sensitivity and output power with a PCB occupation under 3,2 mm², compared with 154mm² for the equivalent discrete solution. With low dispersion over temperature, the BALF-SPI2-02D3 surpasses discrete solutions.
