SX1308IMLTRT

Overview

The SX1308IMLTRT is a digital baseband chip designed for indoor LoRaWAN pico gateways. It integrates the LoRa concentrator IP and operates within a supply voltage range of 3V to 3.6V, consuming 5mA during operation. The device supports a maximum input frequency of 10MHz and functions across a temperature range of 0°C to +70°C. Packaged in a VFQFN-64 format, it provides dual digital Tx & Rx radio front-end interfaces and supports up to 9dB CCR.

Feature Summary

• Integrates LoRa concentrator IP with massive digital signal processing capabilities
• Emulates 49x LoRa demodulators and 1x (G)FSK demodulator simultaneously
• Supports dynamic data-rate adaptation and true antenna diversity operations

Applications

• Indoor LoRaWAN network pico gateways
• Global ISM band gateway implementations
• IoT infrastructure requiring high sensitivity reception

Procurement Notes

Verify that the specific order code matches the required RoHS compliance status, as indicated by the PB Free designation. Confirm the packaging configuration aligns with the 3,000 parts per reel specification. Ensure the component's thermal operating limits are compatible with the intended enclosure design before finalizing procurement orders.

Selection Notes

Select this component when designing indoor gateways requiring high channel density. The chip offers breakthrough capabilities through its ability to emulate nearly fifty parallel demodulation paths. It is suitable for applications demanding negative SNR operation and significant interferer rejection at specific frequency offsets.

Part Context

This part belongs to the Semtech LoRa Core family, specifically engineered for baseband processing in wireless IoT networks. It complements front-end transceivers like the SX1257 or SX1255 to create complete gateway solutions. The series focuses on providing robust connectivity for smart city and industrial IoT deployments.

Replacement Considerations

The SX1302 serves as a related baseband transceiver within the same product family but targets different gateway architectures. Verify interface compatibility and demodulator capacity requirements when considering alternatives within the Semtech portfolio.
