MICRF219AYQS-TR

RF Receivers Overview

The MICRF219AYQS-TR is a superheterodyne RF receiver designed for ASK and OOK modulation schemes, operating within the 300MHz to 450MHz frequency range. It features a sensitivity of -112.5dBm and supports data rates up to 10kbps. The device operates on a supply voltage of 3V to 3.6V with a typical receive current of 4.3mA. It is housed in a 16-pin QSOP surface-mount package and functions within an industrial temperature range of -40°C to 105°C.

RF Receivers Feature Summary

• Integrates RSSI capability for signal strength monitoring
• Supports auto-polling functionality for efficient power management
• Utilizes superheterodyne architecture for improved selectivity

RF Receivers Applications

• Wireless remote control systems
• Low-speed telemetry links
• Security and alarm sensors

RF Receivers Procurement Notes

Verify that the specific suffix 'AYQS' matches the required 16-QSOP package variant. Confirm the 'TR' designation indicates tape-and-reel packaging rather than tube. Ensure the design accounts for the specified 3V to 3.6V supply constraints and the -40°C to 105°C operational temperature limits during integration.

RF Receivers Selection Notes

Select this component for applications requiring low-cost, low-data-rate reception in the sub-GHz band. It is suitable where moderate sensitivity and simple ASK/OOK demodulation are sufficient. Consider the 10kbps maximum data rate limit when designing communication protocols. Evaluate the 16-pin QSOP footprint against available PCB space constraints.

RF Receivers Part Context

This part belongs to the MICRF219 family of single-chip receivers. It is functionally similar to the MICRF219AAYQS but differs in packaging configuration. The series is characterized by its simplicity and low power consumption, targeting basic wireless control applications without complex protocol stacks.
