Description
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-QFAAG0,
nRF51822-QFABB0 and nRF51422-QFAAE0 RF
transceivers.
It is using STMicroelectronics IPD technology on
non-conductive glass substrate which optimize
RF performances.
