STMicroelectronics BALFLB-WL-0xD3 Ultra-Miniature baluns

STMicroelectronics BALFLB-WL-0xD3 Ultra-Miniature baluns integrate a matching network, balun, and harmonics filter. The BALFLB-WL-0xD3 offers customized matching impedance for the STM32WL sub-GHz wireless microcontrollers. Furthermore, the STM BALFLB-WL-0xD3 ultra-miniature baluns implement IPD technology on a nonconductive glass substrate, which optimizes RF performances.
