Baluns use ST’s process integrating high-quality RF passive components on a single glass substrate. As well as balanced/unbalanced conversion, they can also integrate a matching network in a footprint smaller than 1 mm² for the complete function.

ST's latest balun - the 1.2 mm² footprint BALF-NRG-02D3 - is customized for our BlueNRG-1 and new BlueNRG-2 transceivers, reducing RF complexity and providing optimized link budget.
