nRF9131 mini System-in-Package

Low power mini SiP for DECT NR+ and high volume cellular IoT products

The nRF9131 Mini SiP is a powerful solution perfect for DECT NR+ applications. It also supports cellular operations utilizing the same LTE stack as nRF9161. The nRF9131 will simplify traditional chipset-based designs, making it ideal for high-volume cellular IoT applications. With lower integration compared to the nRF9161 SiP, the nRF9131 offers a lower Bill of Materials (BOM). However, it's important to note that cellular end-product certification Non-Recurring Expenses (NRE) will increase depending on needed geographical coverage. This makes it an intriguing choice for global NR+ applications as well high-volume cellular products targeting specific regions.

Main Benefits

  • Perfect for NR+ applications: The nRF9131 excels in NR+ applications, delivering exceptional performance and functionality.
  • Smaller size and flexible sourcing: Smaller than nRF9161 and opens up to use other PMICs with other properties 
  • Feature compatible: Fully feature compatible with nRF9161 with regards to firmware, simple transitions between the two SiPs
  • Reference design available: Bundled with nPM6000 PMIC from Nordic will give similar power consumption as nRF9161
