MICRF022BM-FS24

RF Receivers Overview

The MICRF022BM-FS24 is a single-chip ASK/OOK RF receiver IC operating in the 300MHz to 440MHz frequency range. It features a sensitivity of -97dBm and supports data rates up to 10kbps. The device operates on a supply voltage of 4.75V to 5.5V with a receive current of 2.2mA. It is housed in an 8-SOIC package suitable for surface mount PCB installation. The component functions as a true antenna-in to data-out solution, eliminating manual tuning requirements.

RF Receivers Feature Summary

• Monolithic integration of RF and IF tuning within the IC to eliminate manual calibration
• Direct antenna-to-data interface capability reducing production complexity
• Low power consumption design optimized for battery-operated applications

RF Receivers Applications

• Remote Keyless Entry (RKE) systems
• Wireless sensor networks
• Simplex radio control links

RF Receivers Procurement Notes

Verify component status carefully as this part may be discontinued or subject to limited availability. Confirm RoHS compliance status, as specific variants may not meet current environmental standards. Ensure the 8-SOIC package dimensions match your PCB footprint requirements. Validate that the 300-440MHz frequency band aligns with regional regulatory constraints for your target market.

RF Receivers Selection Notes

Select this component for applications requiring simple ASK/OOK demodulation without complex protocol handling. Consider the reduced feature set compared to the 16-pin MICRF002 variant if space is constrained. Verify that the 10kbps maximum data rate meets system timing requirements. Ensure the operating temperature range of -40°C to 85°C suits the deployment environment.

RF Receivers Part Context

This receiver belongs to the QwikRadio family of low-power UHF receivers designed by Microchip Technology. It serves as an enhanced version of earlier models like the MICRF001/011, offering improved reliability through automatic internal tuning. The 8-pin packaging distinguishes it from the more feature-rich 16-pin counterparts while maintaining core reception capabilities.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The MICRF002 is a related but distinct 16-pin variant with additional features. Direct pin-compatible replacements should be verified against official Microchip obsolescence notices.
