MICRF022BM-FS48

RF Receivers Overview

The MICRF022BM-FS48 is a low-power UHF receiver IC from Microchip Technology, operating within the 300MHz to 440MHz frequency range. It supports ASK and OOK modulation schemes with a maximum data rate of 10 kbps. The device features a receiving current of 2.2mA and a sensitivity of -97dBm. It is housed in an 8-SOIC package and functions as a true antenna-in to data-out monolithic solution. The operational temperature range spans from -40°C to 85°C.

RF Receivers Feature Summary

• Monolithic integration eliminates manual RF and IF tuning requirements
• Supports ASK and OOK modulation for simple demodulation
• Low power consumption suitable for battery-operated applications

RF Receivers Applications

• Remote Keyless Entry (RKE) systems
• Wireless sensor networks
• Simple remote control interfaces

RF Receivers Procurement Notes

Verify the specific suffix FS48 against the official Microchip datasheet to confirm pinout and packaging details. Ensure compatibility with the required 300-440MHz regulatory region. Confirm that the 8-SOIC package dimensions meet PCB layout constraints. Check for lead-free status if RoHS compliance is mandatory for the target assembly process.

RF Receivers Selection Notes

Select this component when a cost-effective, single-chip ASK/OOK receiver is needed for short-range communication. It is appropriate for applications requiring minimal external components and automatic tuning capabilities. Consider the 10 kbps data rate limit and -97dBm sensitivity when designing the link budget for the intended wireless protocol.

RF Receivers Part Context

This part belongs to the QwikRadio family of receivers designed by Micrel, now part of Microchip Technology. It is a simplified 8-pin version of the MICRF002, offering reduced feature sets while maintaining core reception capabilities. The series targets consumer electronics and simple remote control applications requiring reliable UHF reception.

RF Receivers Replacement Considerations

The MICRF022BM-FS12 is a documented alternative within the same product family. Verify pin compatibility and functional equivalence before substitution. No other direct substitutes are confirmed in public documentation.
