RF Receivers datasheet and documents for MICRF219AAYQS-TR

MICRF219AAYQS-TR

RF Receivers Overview

The MICRF219AAYQS-TR is a highly integrated superheterodyne RF receiver designed for ASK and OOK modulation protocols. It operates within the 300MHz to 450MHz frequency range, supporting data rates up to 10kbps. The device features a sensitivity of -112.5dBm and includes an integrated RSSI output. Powered by a 3V to 3.6V supply, it draws 4.3mA during reception. Housed in a 16-QSOP surface-mount package, it functions across a temperature range of -40°C to 105°C.

RF Receivers Feature Summary

Superheterodyne architecture with integrated RSSI for signal strength monitoring
Supports ASK and OOK modulation protocols with auto-poll capability
High sensitivity of -112.5dBm for reliable long-range reception

RF Receivers Applications

General-purpose wireless remote control systems
Industrial sensor networks
Low-speed telemetry applications

RF Receivers Procurement Notes

Verify that the specific suffix 'TR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the operating voltage range aligns with the system's power supply rails. Ensure the 16-QSOP footprint matches the PCB layout design specifications before finalizing procurement orders.

RF Receivers Selection Notes

Select this component when low data rate transmission under 10kbps is sufficient for the application requirements. Consider the -112.5dBm sensitivity limit for link budget calculations. Evaluate the 4.3mA receive current against battery life constraints. Verify compatibility with ASK/OOK encoding schemes used by the transmitter side.

RF Receivers Part Context

This part belongs to the MICRF219 family of single-chip RF receivers from Microchip Technology. It shares architectural similarities with other models in the series but is specifically tuned for the 300-450MHz band. The device integrates necessary filtering and demodulation stages into a compact surface-mount package.
