The Semtech SX1302 is the digital baseband engine at the heart of modern 8-channel LoRaWAN gateways. It demodulates up to 8 LoRa packets simultaneously across all spreading factors while drawing far less power than the previous generation, simplifying thermal design and cutting gateway BOM cost.

Key specifications

• LoRa gateway baseband transceiver; pairs with SX1250/SX1257/SX1250 RF front ends
• 8x LoRa demodulators covering SF5–SF12 plus (G)FSK demodulator
• Up to -141 dBm sensitivity with SX1250 front end
• Fine-timestamp capability for network-centric geolocation
• SPI host interface; single 32 MHz clock; QFN68 package
• -40°C to +85°C operating range

The reference baseband for building high-capacity, low-power LoRaWAN gateways.
