MICRF022BM-FS12

RF Receivers Overview

The MICRF022BM-FS12 is a single-chip ASK/OOK RF receiver IC operating within the 300MHz to 440MHz frequency range. It features a sensitivity of -97dBm and supports maximum data rates up to 10kbps. The device utilizes an 8-pin SOP package and is designed for direct antenna-to-data conversion, eliminating the need for manual tuning or external IF filters.

RF Receivers Feature Summary

• Monolithic ASK/OOK receiver with automatic internal RF and IF tuning
• Direct antenna-in to data-out architecture without external IF filter requirements
• Low-cost solution reducing production complexity through integrated design

RF Receivers Applications

• Remote Keyless Entry (RKE) systems
• Garage door openers
• ISM band applications

RF Receivers Procurement Notes

Verify component status as distributors may list this part as discontinued. Confirm package type matches SOP-8 specifications. Ensure compatibility with 300-440MHz operational bands. Check datasheet revisions for any changes in pinout or electrical characteristics before integration into new designs.

RF Receivers Selection Notes

Select this component for simple ASK/OOK demodulation needs in the sub-GHz range. Consider the reduced feature set compared to the 16-pin MICRF002 variant. Evaluate if the -97dBm sensitivity meets specific link budget requirements. Verify power supply constraints against system voltage levels.
