MICRF229YQS-TR

RF Receivers Overview

The MICRF229YQS-TR is a superheterodyne RF receiver designed for ASK and OOK modulation protocols. It operates within the 400 MHz to 450 MHz frequency range, targeting ISM band applications. The device features a sensitivity of -112 dBm at 20 kbps. It functions on a supply voltage between 3.5 V and 5.5 V, drawing current during reception. The component is housed in a 16-pin QSOP package suitable for surface mount technology.

RF Receivers Feature Summary

• Integrates auto-polling functionality to optimize power consumption by waking up only when valid signals are detected.
• Includes RSSI capability for monitoring received signal strength and squelch function to suppress noise.
• Utilizes a superheterodyne architecture to ensure high selectivity and reliable performance in noisy environments.

RF Receivers Applications

• Wireless remote control systems
• Security alarm sensors
• Industrial telemetry data links

RF Receivers Procurement Notes

Verify that the specific suffix TR indicates tape and reel packaging, distinct from tube variants. Confirm the operating voltage requirements align with the 3.5 V to 5.5 V specification. Ensure the target application frequency falls strictly within the 400 MHz to 450 MHz operational range defined for this part number.

RF Receivers Selection Notes

Select this component when superheterodyne performance is required for ASK/OOK signals in the 400-450 MHz band. Consider the integrated auto-poll feature for battery-powered designs requiring extended standby life. Evaluate the 16-QSOP package constraints against PCB layout space limitations compared to alternative packages.

RF Receivers Part Context

This part belongs to the MICRF229 family of low-cost RF receivers. It shares architectural similarities with other models in the series but is specifically tuned for the 400-450 MHz ISM bands. The TR suffix denotes the reel packaging format used for automated assembly processes.

RF Receivers Replacement Considerations

MICRF229YQS is the tube-packaged equivalent of the same functional device. MICRF229YQS-T5 represents an alternative tape and reel configuration with different quantities. Cross-reference pinouts and electrical specifications before substituting.
