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.
