Features - 50 Ω nominal input / conjugate match to Nordic Semiconductor chips n RF51422CEAA, n RF51422-CDAB, n RF51422-CFAC and n RF51822-CEAA, n RF51822-CDAB, n RF51822-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 n RF51422- CEAA, n RF51422-CDAB, n RF51422-CFAC and n RF51822-CEAA, n RF51822-CDAB, n RF51822-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: n RF51422-CEAA, n RF51422-CDAB, n RF51422CFAC and n RF51822-CEAA, n RF51822-CDAB, n RF51822-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 n RFgo modules.
