General Description Key Features
The SX1302 is a new generation of baseband LoRa chip for LoRaWAN, Class A/B/C, all regions
gateways. It excels in reducing current consumption,
125 kHz LoRa reception with:
simplifies the thermal design of gateways, and reduces the
8 x 8 channels LoRa packet detectors
Bill Of Materials costs, yet it is capable of handling a higher
8 x SF5-SF12 LoRa demodulators
amount of traffic than preceding devices.
8 x SF5-SF10 LoRa demodulators
125 /250 / 500 kHz LoRa demodulator
The high-speed baseband digital engines are clocked from
(G)FSK demodulator
a single 32 MHz clock source, and the chip embeds the
capability to support SF5 and SF6 unlike previous Direct interface to Semtech transceivers
generations. To absorb the additional traffic that the radio
SX1255, SX1257 and SX1250
will be able to detect, more modems are now collaborating.
Single 32 MHz clock
8 of them have been added to specifically handle the
high-speed SF5 and SF6 packets, whilst the 8 others are still

taking care of the SF7-SF12 traffic. The architecture has
been reworked to reduce power consumption very
significantly; it makes it easier to embed the SX1302 in Part Number Delivery Order Quantity
highly-integrated environments where power dissipation

might be a challenge.
The SX1302 is also serialized in production, with a globally
unique 64-bit number. QFN68 Package, operating range from -40 to +85C
Pb-free, Halogen free, RoHS/WEEE compliant product
