Description
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-QFAAG0/GC/FA, nRF51822-QFABB0 and nRF51422-QFAAE0 RF transceivers. The BALF-NRF01D3 uses STMicroelectronics IPD technology on non-conductive glass substrate which optimize RF performances.
