From the makers of the SPIRIT 1 transceiver, STMicroelectronics, comes the BALF-SPI-01D3, an ultra-miniature balun created specifically to interface with the SPIRIT 1 and match its impedance with a 50 Ω nominal input.
The BALF-SPI-01D3 has an incredibly low-profile design (<670 µm) and contains STMicro’s proprietary IPD non-conductive glass to optimize radio frequency performance.
