Product Description

SX1255IWLTRT IC RF TXRX 802.15.4 32WFQFN Semtech Corporation

Product Details



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.




ŠFully flexible I and Q modulator and demodulator
ŠHalf or full-duplex operation
ŠBullet proof RX LNA
ŠAnalog TX and RX pre-filtering
ŠProgrammable tap TX FIR-DAC filter
ŠLinear TX amplifier for both constant and non-constant envelope modulation schemes




ŠIEEE 802.15.4g SUN Multi-PHY Mode Smartgrid
ŠCognitive / SoftwareDefined Radio (SDR)
ŠPb-free, Halogen Free
ŠRoHS / WEEE compliant product
