SX1257 Datasheet | SEMTECH

ion 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 to 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 ponents whilst maintaining maximum design flexibility. All major RF munication parameters are programmable and most of them can be dynamically set. The SX1257 offers support for both narrow-band and wide-band munication modes without the need to modify external ponents. The SX1257 is optimized for low power consumption while offering the provision for high RF output power and channelized operation. True RF™ technology enables a low-cost external ponent count whilst still satisfying ETSI, FCC and ARIB regulations.
