描述 Description

STMicroelectronics BALFHB-WL-05D3 is an ultra-miniature balun. This device

integrates a matching network, balun, and harmonics filter. Matching impedance has

been customized for the STM32WL sub-GHz wireless microcontrollers.

It is using STMicroelectronics IPD technology on a nonconductive glass substrate,

which optimizes RF performances.
