Description
STMicroelectronics BALF-NRG-01D3 is an ultra
miniature balun. The BALF-NRG-01D3 integrates
matching network and harmonics filter. Matching
impedance has been customized for the
BlueNRG ST transceiver (both QFN and WLCSP
versions). It is using STMicroelectronics IPD
technology on non conductive glass substrate
which optimizes RF performance.
