RF Receivers datasheet and documents for MLX71121CLQ-AAA-000-TU

MLX71121CLQ-AAA-000-TU

RF Receivers Overview

The MLX71121CLQ-AAA-000-TU is a superheterodyne RF receiver module by Melexis Technologies NV, operating within the 300MHz to 930MHz frequency range. It supports ASK, FM, and FSK modulation protocols with a maximum data rate of 100kbps and sensitivity of -112dBm. Powered by a 2.1V to 5.5V supply, it consumes 11mA during reception. The component is housed in a 32-QFN (5x5) surface-mount package and functions at temperatures between -10°C and 70°C.

RF Receivers Feature Summary

Dual RF input architecture supporting antenna space diversity, LNA cascading, or differential feeding configurations.

RF Receivers Applications

Automotive remote keyless entry systems
Garage door openers
General-purpose remote control systems

RF Receivers Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level 3 handling requirements. Validate pinout compatibility for 32-QFN footprint integration. Ensure supply chain documentation matches the specific TU tape-and-reel packaging variant.

RF Receivers Selection Notes

Select this model for applications requiring fixed-frequency operation with integrated PLL synthesizers. Consider the dual RF input capability for designs needing enhanced signal reliability through diversity techniques. Evaluate power consumption constraints against the 11mA receive current specification.

RF Receivers Part Context

This part belongs to the MLX71121 series of wireless sensing ICs designed for robust short-range communication. It integrates a fully integrated superheterodyne receiver with an on-chip synthesizer, eliminating external components typically required for frequency generation and filtering in standard RF front-end designs.
