Semtech LoRa LR1121 multiband transceiver

The LoRa LR1121 is an ultralow-power, long-range transceiver offering support for terrestrial, industrial, scientific and medical (ISM) band communications and S-Band support for satellite connectivity. The transceiver is suitable for applications requiring compliance with radio standards, including smart meters, asset tracking applications, parking sensors, environmental sensors and home automation.

The transceiver supports any combination of LoRa, (G)FSK and long-range FHSS (LR-FHSS) modulations. It complies with a broad range of radio standards, including ETSI EN 300 220, FCC CFR 47 Part 15, ARIB and Chinese regulatory requirements. It includes an integrated PA regulator supply selector, simplifying dual power +15/+22 dBm with a single board implementation (sub-GHz).

The transceiver is fully compatible with LoRa Connect SX1261/2/8 devices and the LoRaWAN protocol defined by the LoRa Alliance. Featuring a robust cryptographic engine, it supports AES-128 encryption/decryption-based algorithms.
