Semtech LR2022 LoRa® Plus™ Transceiver
Semtech LR2022 LoRa® Plus™ Transceiver offers a dual-band solution, addressing applications that require global sub-GHz, 2.4GHz, or NTN connectivity while maintaining a cost-effective design. This multi-band transceiver enables a single hardware design for global terrestrial and non-terrestrial networks. Based on Semtech's fourth-generation LoRa IP, the LR2022 is backward-compatible with previous LoRa devices, providing seamless LoRaWAN® compatibility. This transceiver is a subset of the LR2021 series and focuses on LoRa and BLUETOOTH® Low Energy physical layers, as well as FSK-based legacy protocols and third-party stack offerings. The advanced RF and analog architecture supports a multi-region, single-SKU design. Semtech LR2022 LoRa Plus Transceiver delivers superior performance compared to previous LoRa transceivers and reduces the PCB footprint, power consumption, and external BOM costs.
