Overview

The SX1250IMLTRT is a high-performance sub-GHz RF multi-band front-end designed specifically for LoRaWAN gateway applications. It operates across the 150MHz to 960MHz range, providing the necessary up-conversion and down-conversion to interface between digital baseband processors and the RF antenna.

Why Choose This Part

The device features an integrated DC-DC converter that reduces run current to 4.2mA, making it highly efficient for thermally constrained gateway designs. It offers a wide frequency coverage from 150MHz to 960MHz and supports a high output power of up to 22dBm for extended range.

Applications

LoRaWAN Gateways
Acts as the high-sensitivity RF front-end for multi-channel outdoor and indoor gateway designs.
Industrial LPWAN Hubs
Provides reliable long-range communication for industrial sensor networks and asset tracking infrastructure.
Smart City Infrastructure
Used in base stations for utility metering and urban monitoring where wide area coverage is required.

Getting Started

The SX1250 is typically used alongside the SX1302 or SX1303 digital baseband chips; refer to Semtech's LoRa Core gateway reference designs for PCB layout and SPI timing requirements. Hardware evaluation can be performed using Semtech gateway starter kits which include the necessary RF front-end circuitry.
