Base Band Processor for Data Concentrator T/R

The SX1301 digital baseband chip is a massive digital signal processing engine specifically designed to offer breakthrough gateway capabilities in the ISM bands worldwide. It integrates the LORA concentrator IP.The LORA concentrator is a multi-channel high performance transmitter/receiver designed to simultaneously receive several LORA packets using random spreading factors on random channels. Its goal is to enable robust connection between a central wireless data concentrator and a massive amount of wireless end-points spread over a very wide range of distances.The SX1301 is targeted at smart metering fixed networks and Internet of Things applications with up to 5000 nodes per km2 in moderately interfered environment.

• Up to -142.5 dBm sensitivity with SX1257 Tx/Rx front-end (see reference design)
• 70 dB CW interferer rejection at 1 MHz offset
• Able to operate with negative SNR, CCR up to 9 dB
• Emulates 49x LORA demodulators and 1x (G)FSK demodulator
• Dual digital TX&RX radio front-end interfaces
• 10 programmable parallel demodulation paths
• Dynamic data-rate (DDR) adaptation
• True antenna diversity or simultaneous dual-band operation
