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.

Our wide range of integrated baluns includes companion-chips to ST’s latest transceivers, such as:
  - the BALF-NRG-02D3, tailored for our Bluetooth® low energy 2.4GHz radios – BlueNRG-1 and new BlueNRG-2 – in a 1.2 mm² footprint
  - the BALF-SPI2-01D3, designed to be used with S2-LP, ST's sub-1GHz radio.

Both these – as well as other baluns designed for various transceivers from other manufacturers – significantly help reduce RF complexity and provide an optimized link budget.
