The STMicroelectronics BAL-NRF01D3 is an ultraminiature balun integrating a matching network and harmonics filter, specifically optimized for Nordic Semiconductor chipsets like nRF24LE1/AP2 and nRF51 series. Utilizing STMicroelectronics' IPD technology on a non-conductive glass substrate, the BAL-NRF01D3 delivers exceptional RF performance with low insertion loss and minimal imbalance. It's designed for applications requiring a compact, high-performance balun solution, and has been validated by Nordic Semiconductor in their nRFgo modules. The device features a lead-free Flip-Chip package and is available in ECOPACK-compliant grades.
