Just ran across this. Slightly cheaper than SX1308. Anyone have a comparative analysis? They don’t even seem to be on the Semtech site.
Semtech SX1302 LoRa® Gateway Baseband Transceivers reduce current consumption and simplify the thermal design of gateways while decreasing BOM costs. The SX1302 is a new generation of baseband LoRa chip for gateways that is capable of handling a higher amount of traffic than preceding devices.
The high-speed baseband digital engines are clocked from a single 32MHz clock source. The chip embeds the capability to support SF5 and SF6. Eight modems have been added to specifically handle the high-speed SF5 and SF6 packets, while the eight others are currently taking care of the SF7-SF12 traffic.
The SX1302 LoRa Gateway Baseband Transceivers provide an architecture that reduces power consumption significantly, allowing easy embedding in highly-integrated environments where power dissipation might be a challenge. The SX1302 Transceivers are also serialized in production, with a globally unique 64-bit number. The SX1302 has an operating temperature range of -40°C to +85°C.
Semtech SX1250 Multi-band Sub-GHz RF Front End is designed to work with the SX1302 baseband engine, to design a high-performing LoRa® or LoRaWAN gateway. The SX1250 Front End covers any frequency band below 1GHz, making the device ideal for license-free band support.
The SX1250 supports up to +22dBm output power on-chip and can be leveraged to reduce the bill of materials cost when designing a gateway. The need for an external high-end and power-consuming Low Noise amplifier is eliminated due to the extremely low noise figure of the system.
