MICRF230YQS

RF Receivers Overview

The MICRF230YQS is a high-performance RF receiver designed for the ISM band, specifically operating at 433.92MHz with a frequency range of 400MHz to 450MHz. It utilizes a super-heterodyne architecture and supports ASK/OOK modulation protocols. The device offers a sensitivity of -112dBm and a maximum data rate of 20kbps. Powered by a supply voltage between 3.5V and 5.5V, it consumes 6mA during reception. Housed in a 16-QSOP surface-mount package, it operates within a temperature range of -40°C to 105°C.

RF Receivers Procurement Notes

Verify the specific suffix (e.g., YQS vs TR) against your Bill of Materials to ensure correct packaging type. Confirm that the 16-QSOP package dimensions match your PCB footprint requirements. Check RoHS compliance status if required by your manufacturing standards. Ensure the operating voltage range aligns with your system power supply specifications before finalizing procurement.

RF Receivers Selection Notes

Select this component when a low-power, cost-effective solution for sub-GHz communication is required. The integrated squelch and RSSI features simplify circuit design compared to discrete solutions. Consider the 16-QSOP package size for space-constrained designs. Verify compatibility with ASK/OOK transmitters in your system architecture to ensure proper protocol matching and data integrity.

RF Receivers Part Context

The MICRF230 belongs to Microchip's family of single-chip RF receivers targeting ISM bands. It replaces older discrete receiver designs by integrating the mixer, IF amplifier, and demodulator into one package. This integration reduces board space and component count, making it suitable for mass-produced consumer electronics and industrial automation devices requiring simple binary data transmission.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When evaluating alternatives, verify that any replacement maintains the same 400-450MHz frequency range and ASK/OOK modulation support. Ensure the new component matches the 16-QSOP package or requires appropriate adapter design changes.
