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 (868-927 MHz) and the new BALF-SPI2-02D3 (433-470 MHz) , designed to be used with S2-LP, ST's sub-1GHz RF transceiver.
The BALF-SPI2-01D3 is particularly tailored for Sigfox wireless connectivity.
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.
