Bluetooth LE 5.3 System-on-Chip for accurate indoor tracking

The most cost-effective solution for locator tags in RTLS (Real-time locating system), asset tracking and item finding application

The BlueNRG-LPS is a programmable Bluetooth®LE SoC. It embeds state-of-the-art 2.4 GHz proprietary RF radio IPs and combines unparalleled performance with a very long battery lifetime. It is compliant with Bluetooth®LE SIG core specification 5.3, which addresses point-to-point connectivity and Bluetooth Mesh networking.

The BlueNRG-LPS SoC helps developers boost the wireless performance of their applications, thanks to a greater range and secure multi-link connections.

To further optimize size and simplify the design implementation the MLPF-NRG-01D3 integrating the matching network and the low pass filter in a single chip has been validated with the BLUENRG-LPS SoC.
