MICRF230YQS-TR

RF Receivers Overview

The MICRF230YQS-TR is a superheterodyne RF receiver designed for the 400MHz to 450MHz ISM band, specifically optimized for 433.92MHz applications. It supports ASK/OOK modulation with a maximum data rate of 20kbps and achieves a sensitivity of -112dBm. The device operates on a single supply voltage ranging from 3.5V to 5.5V, drawing a receive current of 6mA. Key integrated features include automatic gain control, RSSI output, squelch functionality, and an auto-poll mode. It is housed in a 16-QSOP surface-mount package suitable for industrial temperatures between -40°C and 105°C.

RF Receivers Feature Summary

• Superheterodyne architecture provides image rejection and high selectivity for reliable signal reception.
• Integrated RSSI and squelch circuits enable robust link quality monitoring and noise filtering.
• Auto-poll mode capability supports efficient low-power communication protocols.
• On-board tracking antenna input simplifies circuit design and impedance matching.

RF Receivers Applications

• ISM band wireless sensor networks
• Remote keyless entry systems
• Industrial telemetry and monitoring
• Security alarm systems

RF Receivers Procurement Notes

Verify that the specific application frequency aligns with the 400-450MHz operational range. Confirm power supply stability within the 3.5V to 5.5V limits to ensure proper receiver performance. Check for required interface compatibility with downstream digital logic. Ensure thermal management meets the -40°C to 105°C operating specification. Review datasheet for pinout configuration against PCB layout requirements.

RF Receivers Selection Notes

Select this component when superheterodyne performance is required over direct-conversion designs for better interference rejection. Consider the 6mA current consumption for battery life calculations in portable devices. Evaluate the need for built-in squelch and RSSI features to simplify system-level filtering. Verify that the 16-QSOP package fits the available board space constraints.

RF Receivers Part Context

This part belongs to the Microchip MICRF230 family of RF receivers. It is manufactured by Microchip Technology, formerly incorporating Micrel products. The device is distinct from the MICRF213 series, which operates at lower frequencies (300-350MHz) and different speeds. The MICRF230 focuses on higher frequency ISM bands with enhanced analog front-end capabilities.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. Direct replacements should be verified through official Microchip obsolescence notices or authorized distributor cross-reference tools. Generic alternatives may lack the specific superheterodyne architecture and integrated features of the MICRF230.
