DATASHEET

SX1276/77/78/79 - 137 MHz to 1020 MHz Low Power Long Range Transceiver

GENERAL DESCRIPTION

The SX1276/77/78/79 transceivers feature the LoRaTM long

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.

LoRaTM 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.

These devices also support high performance (G)FSK

modes for systems including WMBus, IEEE802.15.4g. The

SX1276/77/78/79 deliver exceptional phase noise,

selectivity, receiver linearity and IIP3 for significantly lower

current consumption than competing devices.
