Sensor transceiver module LR2021

2.4 GHzEDGEFSK

The LoRa Connect/LoRa Edge/LoRa Plus portfolio consists of sub-GHz, 2.4 GHz and multi-band transceiver chips and reference designs for sensors and trackers. 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. The device additionally features expanded physical layer modulations for fast long-range communication (FLRC) and is compatible with various low-power wireless protocols including Amazon Sidewalk, Meshtastic, W-MBUS, Wi-SUN FSK, and Z-Wave when integrated with third-party stack offerings. The LR2021 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™ LR2021 include: Terrestrial and NTN, sub-GHz, 2.4 GHz ISM bands and licensed S-band radio Multi-PHY compatibility enables LP wireless protocols with third-party stacks FLRC up to 2.6 Mbps, LoRa up to 200 kbps, FSK, OOK, O-QPSK and LR-FHSS modulations Multi-region operation with single switch-less front-end design +22 dBm to -10 dBm Transmitter, offering best-in-class energy efficiency Multi-SF Receiver with low noise figure, Improved CAD and best LoRa sensitivity down to -142 dBm @ SF12/125 kHz Increased frequency offset tolerance obviating TCXO and large thermal relief
