BALF-NRF01E3 50 nominal input / conjugate match balun to nRF51822-QFAA /AB/AC and nRF51422-QFAA/AB/AC with integrated filter Datasheet production data Applications 2.45 GHz balun with integrated matching network Matching optimized for following chipsets: nRF51822-QFAA/AB/AC and nRF51422-QFAA/AB/AC (see Figure 19: nRF51822 and nRF51422 compatibility matrix). WHUPLQDO /* Description STMicroelectronics BALF-NRF01E3 is an ultraminiature balun. The BALF-NRF01E3 integrates matching network in a monolithic glass Features substrate. Matching impedance has been customized for the nRF51822-QFAA/AB/AC and Low insertion loss nRF51422-QFAA/AB/AC RF transceivers. Low amplitude imbalance It uses STMicroelectronics IPD technology on Low phase imbalance non-conductive glass substrate which optimizes RF performance.
