SX1303 Image

The SX1303 from Semtech is a LoRa Baseband Processor Chip that has been developed for gateways. It has been designed to cut down current consumption, simplify thermal design, lower the Bill Of Materials cost and reduce the overall size of gateways. It has an Rx sensitivity of up to -141 dBm with the SX1250 Tx/Rx Front end. The chip supports 8 x 8 channels LoRa packet detectors, 8 x SF5-SF12 LoRa demodulators, and 8 x SF5-SF10 LoRa demodulators. The chip is available in the QFN68 package and is ideal for smart metering, security, smart agriculture, logistics tracking, and IoT applications. 

The SX1303 is size and pin-compatible with SX1302 and also has a new Fine Timestamp capability that enables Time Difference of Arrival (TDOA) network-based geolocation.
