The Semtech SX1302 is a next-generation baseband chip designed for LoRa® gateways. It reduces current consumption, simplifies thermal design, lowers the Bill of Materials cost, and is capable of handling more traffic compared to previous devices. The high-speed baseband digital engines are driven by a single 32 MHz clock source, and the chip adds support for spreading factors SF5 and SF6, which were not available in earlier generations.
To manage the additional traffic, the SX1302 integrates sixteen modems: eight dedicated to high-speed SF5 and SF6 packets and eight handling SF7 to SF12 traffic. Its reworked architecture delivers significant power savings, making the chip easier to integrate in compact environments where power dissipation can be a challenge. Additionally, every SX1302 is serialised during production and comes with a unique globally assigned 64-bit identification number.
