SX1280IMLTRT Product Details

General Description 

The SX1280IMLTRT and SX1281 transceivers provide ultra long range communication in the 2.4 GHz band with the linearity to withstand heavy interference. This makes them the ideal solution for robust and reliable wireless solutions. They are the first ISM band transceiver IC of their kind to integrate a time-of-flight functionality, opening up application solutions to track and localize people, pets, drones, or objects in a factory. These long range 2.4 GHz products include multiple physical layers and modulations to optimize long range communication at high data rate for video and security applications. Very small products for wearables can easily be designed thanks to the high level of integration and the ultra-low current consumption which allows the use of miniaturized batteries. The radio is fully compliant with all worldwide 2.4 GHz radio regulations including EN 300 440, FCC CFR 47 Part 15 and the Japanese ARIB STD-T66. The level of integration, low consumption and ranging function within the long range 2.4 GHz product line enable enhanced connectivity and provide additional functionality to a new generation of previously unconnected devices and applications.
