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 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.
