SX1261 and SX1262 LoRa® Transceivers

By Semtech 123

SX1261 and SX1262 LoRa® Transceivers

Semtech’s SX1261 and SX1262 are sub-GHz radio transceivers that support LoRa modulation for LPWAN (low power wide-area network) and (G)FSK (Gaussian frequency shift keying) modulation. The transceivers are highly configurable to meet different applications utilizing the global LoRaWAN™ standard and comply with the physical layer requirements of the LoRaWAN specification released by the LoRa Alliance™.

The devices are designed for long-range wireless applications and support long battery life. The SX1261 can transmit up to +15 dBm and SX1262 can transmit up to +22 dBm with highly efficient integrated power amplifiers. The radio is suitable for systems targeting compliance with radio regulations including but not limited to ETSI EN 300 220, FCC CFR 47 Part 15, China regulatory requirements, and the Japanese ARIB T-108. Continuous frequency coverage from 150 MHz to 960 MHz allows the support of all major sub-GHz ISM bands around the world.
