1. The LR68-NA-C module is sub-GHz radio transceivers that are ideal for long-range wireless applications. These devices support LoRa® modulation for LPWAN use cases and (G) FSK modulation for legacy use cases. The devices are highly configurable to meet different application requirements utilizing the global LoRaWAN® standard or proprietary protocols.
2. The devices are designed to comply with the physical layer requirements of the LoRaWAN specification released by the LoRa Alliance™.
3. The radio is suitable for systems targeting compliance with radio regulations including but not limited to ETSI EN 300 220, FCC CFR 47 Part 15, China regulatory requirements and the Japanese ARIB T-108. Continuous frequency coverage from 150 MHz to 960 MHz allows the support of all major sub-GHz ISM bands around the world.
1.Analog Front End: the transmit and receive chains, as well as the data converter interface to ensuing digital blocks. The LR68NA-C transceiver is capable of delivering up to +21 dBm under the battery supply.
2.Digital Modem Bank: a range of modulation options is available in the LR68NA-C:
w LoRa® Rx/Tx, BW = 125 -250 - 500 kHz
w LoRa® SF = 5 - 6 - 7 - 8 - 9 for BW = 125 kHz
w LoRa® SF = 5 - 6 - 7 - 8 - 9 - 10 for BW = 250 kHz
w LoRa® SF = 5 - 6 - 7 - 8 - 9 - 10 - 11 for BW = 500 kHz
