STMicroelectronics Balun Transformers
STMicroelectronics Balun Transformers use ST's process of integrating high-quality RF passive components on a single glass substrate. In addition to balanced/unbalanced conversion, these baluns can incorporate a matching network in a footprint smaller than 1mm2 for the complete function. The baluns are designed using STMicroelectronics Integrated Passive Device (IPD) technology on a non-conductive glass substrate to optimize RF performance. These baluns include companion chips to ST's transceivers, help significantly reduce RF complexity, and provide an optimized link budget. Balun transformers integrate three functions: impedance matching, 50Ω nominal impedance, and harmonic filter.
