SEMTECH SX1302IMLTRT

The SX1302 is a new generation of baseband LoRa chip for gateways. It excels in reducing current consumption, simplifies the thermal design of gateways, and reduces the Bill Of Materials costs, yet it is capable of handling a higher amount of traffic than preceding devices. The high-speed baseband digital engines are clocked from a single 32 MHz clock source, and the chip embeds the capability to support SF5 and SF6 unlike previous generations. To absorb the additional traffic that the radio will be able to detect, more modems are now collaborating. 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 highly-integrated environments where power dissipation might be a challenge. The SX1302 is also serialized in production, with a globally unique 64-bit number.
