RF Receivers Procurement Notes

Verify the manufacturer marking on the component body to confirm authenticity, as Microchip Technology acquired Micrel Semiconductor which originally produced this part. Ensure the suffix 'BM' corresponds to the specific tape-and-reel or tube packaging variant required for your assembly process. Cross-reference the date code against current production status to avoid obsolete stock issues during procurement.

RF Receivers Selection Notes

Select this component when designing systems requiring simple ASK/OOK demodulation at UHF frequencies without complex baseband processing. It is suitable for applications prioritizing low power consumption and cost-effectiveness over high data throughput. Consider the 16-lead SOIC footprint constraints and verify that the 5V logic levels align with the host microcontroller interface requirements.

RF Receivers Part Context

This receiver belongs to the QwikRadio family of integrated circuits, originally developed by Micrel before its acquisition by Microchip Technology. The series targets cost-sensitive wireless applications where minimal external components are desired. The MICRF009BM represents a specialized solution for fixed-frequency or lightly tuned UHF reception tasks in consumer and industrial electronics.

RF Receivers Replacement Considerations

The MICRF001BN is listed as a comparable alternative within the same product category. Verify pin compatibility and functional equivalence before substitution. No other direct public substitutes are confirmed in available documentation.
