General Description
SX1261 and SX1262 sub-GHz radio transceivers are ideal for long range wireless applications. Both devices are designed for long battery life with just 4.2 mA of active receive current consumption. The SX1261 can transmit up to +15 dBm and the SX1262 can transmit up to +22 dBm with highly efficient integrated power amplifiers.
These devices support LoRa® modulation for LPWAN use cases and (G)FSK modulation for legacy use cases. The devices are highly configurable to meet different application requirements utilizing the global LoRaWANTM standard or proprietary protocols.
The devices are designed to comply with the physical layer requirements of the LoRaWANTM specification released by the LoRa AllianceTM.
The radio is suitable for systems.
