00 — Overview

What the SX1262 family does

The SX1261/2 are long-range, low-power sub-GHz RF transceivers available in SX1261 and SX1262 variants. These devices support LoRa modulation for LPWAN applications and (G)FSK for legacy systems, operating across 150 MHz to 960 MHz. The SX1261 transmits up to +15 dBm while the SX1262 reaches +22 dBm. Both maintain just 4.2 mA active receive current. They are ideal for smart meters, supply chain logistics, building automation, agricultural sensors, and asset tracking. The integrated analog front end and data conversion engine ensure high efficiency for battery-powered IoT devices.
