MICRF022BN

RF Receivers Overview

The MICRF022BN 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 a maximum data rate of 10kbps. The device utilizes ASK or OOK modulation protocols. It is housed in an 8-DIP surface mount package. The component functions as a true antenna-in to data-out monolithic solution for low-power UHF applications.

RF Receivers Feature Summary

• Monolithic single-chip design integrating RF reception and demodulation
• Supports ASK and OOK modulation protocols for remote keyless entry
• Operates within the 300MHz to 440MHz UHF band

RF Receivers Applications

• Remote Keyless Entry (RKE) systems
• Low power UHF receiver circuits
• Consumer electronic control interfaces

RF Receivers Procurement Notes

Verify part status carefully as the MICRF022BN is listed as obsolete in multiple distributor databases. Confirm availability through authorized channels or consider equivalent active components if long-term supply stability is required. Check RoHS compliance status against specific project requirements, as some sources indicate non-compliance while others list standard packaging.

RF Receivers Selection Notes

Select this component for simple ASK/OOK demodulation needs in the 300-440MHz range. Ensure the application requires a data rate up to 10kbps and can accommodate the specified -97dBm sensitivity. The DIP-8 package suits prototyping or low-volume production where surface mount density is not critical. Verify compatibility with existing antenna designs for optimal performance.

RF Receivers Part Context

The MICRF022 series belongs to the QwikRadio family of low-power UHF receivers originally developed by Micrel Semiconductor, now part of Microchip Technology. This line focuses on simplified integration for remote control applications. The BN suffix typically denotes the specific package configuration and pinout compatible with standard DIP footprints, distinguishing it from other variants like the BM or YM series.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers are not explicitly documented in the provided source material. Given the obsolete status, consult Microchip technical support for current recommended replacements or evaluate generic ASK receivers with matching frequency and sensitivity specifications.
