SX1257 Datasheet PDF - Semtech Corporation

●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.
