GENERAL DESCRIPTION
The SX1257 is a highly integrated RF front-end to digital I and Q
modulator/demodulator Multi-PHY mode transceiver capable of
supporting multiple constant and non-constant envelope modulation
schemes. It is designed to operate over the 862 - 960 MHz European,
North American and Japanese ISM (Industrial, Scientific and
Medical) license exempt frequency bands. Its highly integrated
architecture allows for a minimum of external components whilst
maintaining maximum design flexibility. All major RF communication
parameters are programmable and most of them can be dynamically
set.
