Semtech SX1276
LoRa Core™ 137MHz to 1020MHz Long Range Low Power Transceiver

The SX1276/77/78/79 transceivers feature the LoRa® long range modem that 
provides ultra-long range spread spectrum communication and high 
interference immunity whilst minimizing current consumption.

Using Semtech’s patented LoRa 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 +20dBm 
power amplifier yields industry leading link budget making it optimal 
for any application requiring range or robustness. LoRa also provides 
significant advantages in both blocking and selectivity over 
conventional modulation techniques, solving the traditional design 
compromise between range, interference immunity and energy consumption.
