Overview
Using fourth-generation LoRa® IP supporting both terrestrial and SATCOM networks in the sub-GHz, 2.4 GHz ISM bands and licensed S-band. The transceiver is designed to be backward compatible with previous LoRa devices, ensuring seamless LoRaWAN® compatibility. This device is a sub-set of the LR2021, focusing on LoRa and Bluetooth LE Physical Layers, as well as FSK-based legacy protocols with third-party stack offerings. The LR2022 features an advanced RF and analog architecture that supports a multi-region, single-SKU design, reducing external BOM costs, PCB footprint, and power consumption, while offering superior performance compared to previous LoRa transceivers.
Features
Key features of the LoRa Plus™ LR2022 include:
- Terrestrial sub-GHz, 2.4 GHz ISM bands and NTN (L and S) bands
- Multi-PHY compatibility enables LP wireless protocols with third-party stacks
- LoRa up to 125 kbps, FSK, OOK and LR-FHSS modulations
- Multi-region operation with single switch-less front-end design
- +22 dBm to -10 dBm Transmitter in SubGHz and +12dBm to -15dBm in the 2.4GHz band, offering best-in-class energy efficiency
- Multi-SF Receiver with low noise figure, Improved CAD and best LoRa sensitivity down to -141.5 dBm @ SF12/125 kHz
- Increased frequency offset tolerance obviating TCXO and large thermal relief
