SX1239IMLTRT

RF Receivers Overview

The SX1239IMLTRT is a low-power integrated UHF receiver manufactured by Semtech Corporation. It operates within a frequency range of 290 MHz to 1.02 GHz, supporting bands such as 433, 868, and 915 MHz. The device utilizes FSK and GFSK modulation schemes with a maximum data rate of 300 kbps. Electrical specifications include a supply voltage range of 1.8 V to 3.6 V and an operating current of 16 mA. It functions within a temperature range of -40°C to +85°C and is housed in a 24-pin QFN package.

RF Receivers Feature Summary

• Highly integrated UHF receiver architecture designed for low power consumption
• Supports FSK and GFSK modulation protocols for reliable wireless communication
• Wide operational frequency coverage spanning 290 MHz to 1.02 GHz

RF Receivers Applications

• Wireless sensor networks requiring long-range sub-GHz connectivity
• Remote control systems for industrial automation
• Low-power IoT devices utilizing ISM band frequencies

RF Receivers Procurement Notes

Verify the specific suffix LTRT corresponds to the required tape and reel packaging configuration before ordering. Confirm that the 24-QFN pinout matches the target PCB footprint design. Ensure the component meets RoHS compliance standards for the intended market. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and production status.

RF Receivers Selection Notes

Select this component when a dedicated receiver solution is preferred over a full transceiver to optimize system cost and power usage. The wide frequency range allows flexibility across global ISM bands without hardware changes. Verify that the host microcontroller supports the necessary SPI interface for register configuration and data retrieval.

RF Receivers Part Context

This part belongs to the Semtech SX123x series of highly integrated RF receivers. It shares architectural similarities with other members like the SX1232 but lacks the transmitter functionality found in transceivers. The series targets applications needing robust reception capabilities in noisy environments while maintaining minimal power draw.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacement requires verification of pin compatibility and register-level software migration.
