Description

General part information

BALF Series

STMicroelectronics BALF-NRF01D3 is an ultraminiature balun. The BALF-NRF01D3 integrates matching network in a monolithic glass substrate. Matching impedance has been customized for the nRF51822-QFAA/QFAB, and nRF51422-QFAA/QFAB RF transceivers.

The BALF-NRF01D3 uses STMicroelectronics IPD technology on non-conductive glass substrate which optimize RF performance.
