MICRF219AAYQS

RF Receivers Overview

The MICRF219AAYQS is a superheterodyne RF receiver designed for ASK and OOK modulation protocols within the 300MHz to 450MHz frequency range. It operates on a supply voltage of 3V to 3.6V, consuming 4.3mA during reception. The device features integrated RSSI and achieves a sensitivity of -112.5dBm. Packaged in a 16-QSOP surface-mount format, it supports data rates up to 10kbps and functions reliably across an industrial temperature range of -40°C to 105°C.

RF Receivers Feature Summary

• Superheterodyne architecture with integrated automatic gain control
• Built-in Received Signal Strength Indicator (RSSI) functionality
• Supports ASK and OOK modulation protocols without external IF filters
• Includes auto-polling capability for efficient power management

RF Receivers Applications

• ISM band wireless sensor networks
• Remote Keyless Entry (RKE) systems
• Garage door opener receivers
• Low-speed telemetry applications

RF Receivers Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with RoHS and REACH environmental standards required by your manufacturing process. Confirm that the 16-QSOP footprint matches your PCB design guidelines before finalizing procurement orders.

RF Receivers Selection Notes

Select this component when designing systems requiring high sensitivity for low-data-rate ASK/OOK signals in the sub-GHz ISM bands. The integrated RSSI provides signal quality monitoring, while the superheterodyne topology ensures robust performance compared to direct-conversion alternatives. Consider the 16-QSOP package constraints for space-limited industrial enclosures.

RF Receivers Part Context

This part belongs to the MICRF219A family of single-chip RF receivers from Microchip Technology. It serves as a specialized solution for simple, cost-effective wireless communication links. The device integrates most front-end functions onto a single silicon die, reducing external component count and simplifying the overall system design for manufacturers.
