BALF-NRG-01D3

BALF-NRG-01D3 50 ohm nominal input / conjugate match balun balun to BlueNRG tranceiver, with integrated harmonic filter Datasheet - production data Flip-Chip (4 bumps) package Features  50 Ω nominal input / conjugate match to BlueNRG device  Low insertion loss  Low amplitude imbalance  Low phase imbalance  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 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.
