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.

■ Wafer level chip scale package (WLCSP) Benefits
■ Very low profile: < 670 µm
■ High RF performance
■ RF BOM reduction
■ Small footprint

Applications
■ Bluetooth low energy impedance matched balun filter
■ Optimized for ST BlueNRG RFIC
