STMicroelectronics Surface Mount Chip Balun

STMicroelectronics BALF-NRF01E3 is an ultraminiature balun. The BALF-NRF01E3 integrates matching network in a monolithic glass substrate. Matching impedance has been customized for the nRF51822-QFAA/AB/AC and nRF51422-QFAA/AB/AC RF transceivers. It uses STMicroelectronics IPD technology on non-conductive glass substrate which optimizes RF performance.
