RF Receivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific revision status as the RX5501 may be subject to product discontinuation notices. Ensure compatibility with existing design specifications regarding the 315MHz frequency band and ASK/OOK modulation requirements before finalizing procurement orders.

RF Receivers Selection Notes

Select the RX5501 when a compact, low-power solution is required for 315MHz ASK/OOK applications. Consider its -110.5dBm sensitivity for long-reception needs in noisy environments. Evaluate the 3.1mA receive current against power budget constraints. Ensure the SM-20L footprint fits the target PCB layout and that the 2.2V to 3.7V supply range aligns with the system power architecture.

RF Receivers Part Context

The RX5501 belongs to the RX55 series of RF receivers from Murata Electronics, designed for cost-effective and space-constrained wireless applications. It shares architectural similarities with other models like the RX5500 but is specifically tuned for the 315MHz ISM band. This series emphasizes hybrid amplifier-sequenced technology to balance performance and power efficiency.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The RX5500 is a related model operating at 433.92MHz and may require circuit adjustments due to frequency differences. Verify availability of alternative frequencies or packages if the RX5501 is discontinued.
