STMicroelectronics' BALF-SPI2-02D3 ultra-miniature balun with Rx and Tx impedance optimized for S2-LP RF transceivers at 433 MHz. The BALF-SPI2-02D3 single-component solution simplifies RF complexity implementation by providing an optimized Rx sensitivity and output power with a PCB occupation under 3.2 mm², compared with 154 mm² for the equivalent discrete solution. With low dispersion overtemperature, the BALF-SPI2-02D3 surpasses discrete solutions.
