BAL-NRF02D3 50 ohm nominal input / conjugate match balun to nRF51822CEAA/CDAB/CFAC and nRF51422-CEAA/CDAB/CFAC Datasheet - production data Flip-Chip (5 bumps) package Features  50 Ω nominal input / conjugate match to Nordic Semiconductor chips nRF51422CEAA, nRF51422-CDAB, nRF51422-CFAC and nRF51822-CEAA, nRF51822-CDAB, nRF51822-CFAC  Low insertion loss  Low amplitude imbalance  Low phase imbalance  Small footprint: < 1.2 mm2 Benefits  Very low profile < 570 μm after reflow with pad 260 µm max. or < 585 μm after reflow with pad 220 µm typ.  High RF performance  RF BOM and area reduction Applications  2.45 GHz impedance matched balun filter  Optimized for Nordic's chip set nRF51422- CEAA, nRF51422-CDAB, nRF51422-CFAC and nRF51822-CEAA, nRF51822-CDAB, nRF51822-CFAC Description STMicroelectronics BAL-NRF02D3 is an ultraminiature balun. The BAL-NRF02D3 integrates matching network and harmonics filter. Matching impedance has been customized for the following Nordic Semiconductor circuits: nRF51422-CEAA, nRF51422-CDAB, nRF51422CFAC and nRF51822-CEAA, nRF51822-CDAB, nRF51822-CFAC. The BAL-NRF02D3 uses STMicroelectronics IPD technology on non-conductive glass substrate which optimizes RF performance. The BAL-NRF02D3 has been tested and approved by Nordic Semiconductor in the nRFgo modules.
