Semtech expands LoRa Plus transceiver lineup
Semtech’s LR2022 and LR2012 LoRa Plus transceivers target a range of IoT deployments, from sub-GHz sensors to global multiband non-terrestrial networks (NTNs). The devices are subsets of the previously announced LR2021 and share its fourth-generation LoRa Plus IP core.
Both transceivers provide LoRa receiver sensitivity down to −141.5 dBm at SF12 with 125-kHz bandwidth and data rates up to 125 kbps for LoRa and 2 Mbps with FSK modulation. A single, switchless front-end design enables multiregion operation, while increased frequency offset tolerance improves performance across different frequency bands.
The dual-band LR2022 covers terrestrial sub-GHz, 2.4-GHz ISM, and NTN L and S bands and supports LoRaWAN, Bluetooth LE, and FSK-based legacy protocols. The sub-GHz-only LR2012 supports LoRaWAN, Wi-SUN, wireless M-Bus, and FSK-based proprietary protocols. Transmitter output power ranges from +22 dBm to −10 dBm in the sub-GHz band for both devices, while the LR2022 provides +12 dBm to −15 dBm in the 2.4-GHz band.
The LR2022 and LR2012 transceivers are now in production.
