SX1302C915GW1

Overview

The SX1302C915GW1 is a LoRa Core digital baseband chip designed for LoRaWAN network gateways, operating at the 915MHz frequency. It features an SPI interface and operates within a temperature range of -40°C to +85°C. The device utilizes a QFN68 package with dimensions of 7 mm x 7 mm x 0.75 mm. It supports up to eight simultaneous LoRa demodulators and includes GFSK demodulation capabilities. The component interfaces directly with Semtech transceivers such as the SX1250 series.

Feature Summary

• Supports up to eight simultaneous LoRa demodulators for high-capacity gateway applications
• Direct interface compatibility with Semtech SX1250, SX1255, SX1257, and SX1258 transceivers
• Integrated GFSK demodulator alongside LoRa processing capabilities

Applications

• LoRaWAN network gateway baseband processing
• Full duplex gateway applications
• Listen Before Talk (LBT) and spectral scan implementations

Procurement Notes

Verify end-of-life status before procurement as the component may be discontinued. Confirm availability through authorized distributors as stock levels are limited. Ensure the specific 915MHz regional variant matches target deployment requirements. Check for updated datasheets regarding any design-in changes or substitute recommendations from Semtech.

Selection Notes

Select this model specifically for 915MHz regulatory regions requiring LoRaWAN gateway baseband processing. Compare against the generic SX1302IMLTRT if regional frequency locking is not required. Ensure system design accommodates the QFN68 package thermal and mechanical constraints. Verify compatibility with the intended Semtech front-end transceiver chain for optimal sensitivity performance.

Part Context

Part of the SX1302 LoRa Core family, this chip reduces current consumption and simplifies thermal design for gateways while handling increased traffic compared to previous generations. It serves as the central baseband processor for multi-channel LoRa reception in IoT infrastructure.

Replacement Considerations

Public confirmed substitutes: None listed. The generic SX1302IMLTRT shares the same core functionality but lacks the fixed 915MHz region lock.
