The SX1276/77/78/79 transceivers feature the LoRaTM
range modem that provides ultra-long range spread
spectrum communication and high interference immunity
whilst minimising current consumption.
Using Semtech’s patented LoRaTM modulation technique
SX1276/77/78/79 can achieve a sensitivity of over -148dBm
using a low cost crystal and bill of materials. The high
sensitivity combined with the integrated +20 dBm power
amplifier yields industry leading link budget making it
optimal for any application requiring range or robustness.
