Semtech SX1261/SX1262 LoRa Transceivers
Semtech SX1261 and SX1262 LoRa® Transceivers are low-power, sub-GHz radio transceivers designed to comply with the physical layer requirements of the LoRaWAN™ specification. With support for LoRa modulation for LPWAN use cases and (G)FSK modulation for legacy use cases, Semtech SX1261/SX1262 radio transceivers are compatible with existing LoRaWAN networks and can support proprietary protocols.Consuming only 4.2mA of active receive current, the transceivers offer long battery life in long-range wireless applications. The SX1261 transceiver can transmit up to +15dBm while the SX1262 can transmit up to +22dBm with highly efficient integrated power amplifiers.
In order to support all major sub-GHz ISM bands around the world, SX1261/SX1261 LoRa Transceivers provide continuous frequency coverage from 150MHz to 960MHz. The radio is well-suited for systems requiring compliance with radio regulations such as ETSI EN 300 220, FCC CFR 47 Part 15, China regulatory requirements, and the Japanese ARIB T-108.
