Description
STMicroelectronics BAL-NRF01D3 is an
ultraminiature balun. The BAL-NRF01D3
integrates matching network and harmonics filter.
Matching impedance has been customized for the
following Nordic Semiconductor circuits:
nRF24LE1 QFN-32 pins, nRF24AP2-1CH,
nRF24AP2-8CH, nRF51422 and nRF51822.
The BAL-NRF01D3 uses STMicroelectronics IPD
technology on non-conductive glass substrate
which optimize RF performances.
The BAL-NRF01D3 has been tested and
approved by Nordic Semiconductor in their
nRF2723 and nRF2752 nRFgo modules.
