LF7611 is a compact, low power, bidirectional transcevier module for 863~928MHz band, provides ultra-long range spread spectrum communication and high inteference immunity whilst minimissing current consumption. It Integrated with Semtech's SX1276 RF transceiver, high sensitivity of over -139dBm combined with the integrated +18.6dBm power amplifer yields industry leading link budget making LF7611 optimal for any application requiring range or robustness. The LoRaTM modulation, in contrast to conventional modulation techniques , permits an increase in link budget and increases immunity to in-band interference. It achieves sensitivities 8dBm batter than traditional FSK modulation and it also provides significant advantages in both blocking and slectivity.
