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 and
nRF24AP2-8CH. 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 nRFgo module.
