BALF-NRF01J5 Ultra-Thin Balun

STMicroelectronics' BALF-NRF01J5 50 Ω ultra-thin balun with integrated harmonic filter for nRF51822-CTAA/CTAC

STMicroelectronics' BALF-NRF01J5 is an ultraminiature extra-thin balun that integrates matching network and harmonics filter. Matching impedance has been customized for the nRF51822-CTAA and CTAC WLCSP Nordic Semiconductor circuits. Based on IPD technology on high resistivity silicium, it optimizes the RF performance. The BALF-NRF01J5 has been tested and approved by Nordic Semiconductor.
