50Ω nominal input / conjugate match balun to nRF51x22-QFAA, nRF51x22-QFAC, nRF51822-QFABBx and nRF51422-QFABAx with integrated filter

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.
