General Description
The SX1280 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 .
