Semtech SX1303
LoRa Core™ Digital Baseband Chip for Gateways Based on the LoRaWAN® Protocol
The SX1303 is a new generation of LoRa® baseband processor for gateways. It is size and pin compatible with SX1302 and like SX1302, it excels in cutting down current consumption, simplifying thermal design, lowering Bill Of Materials cost, and reducing overall size of gateways. In addition to supporting all the features of SX1302, SX1303 introduces a new Fine Timestamp capability that enables Time Difference of Arrival (TDOA) network-based geolocation.
