BAL-NRF01D3 STMicroelectronics

BAL-NRF01D3 50 nominal input / conjugate match balun to nRF51422-QFAA, nRF24LE1, nRF51822-QFAA/AB, with integrated harmonic filter Datasheet - production data Description STMicroelectronics BAL-NRF01D3 is an ultraminiature balun. The device integrates matching network and harmonics filter. Matching impedance has been customized for the following Nordic Semiconductor circuits: nRF24LE1 QFN- 32 pins, nRF24AP2-1CH, nRF24AP2-8CH, nRF51422-QFAA (build code CA/C0), nRF51822-QFAA (build code CA/C0) and nRF51822-QFAB (build code AA/A0). Lead-free Flip-Chip (5 bumps) package The device uses STMicroelectronics IPD technology on a non-conductive glass substrate to optimize RF performance. Features The BAL-NRF01D3 has been tested and 50 nominal input / conjugate match to approved by Nordic Semiconductor in their Nordic Semiconductor chips nRF24LE1 nRF2723 and nRF2752 nRFgo modules.
