RFM65W-868-S2

RF Receivers Overview

The RFM65W-868-S2 is a highly integrated Sub-GHz receiver module operating in the 868 MHz ISM band. It utilizes FSK, GFSK, GMSK, MSK, and OOK modulation schemes to support data rates up to 300 kbps. The device features a receiver sensitivity of -120 dBm and operates on a supply voltage range of 1.8V to 3.6V. Communication with the host system is facilitated via an SPI interface. Designed for low-cost applications, it provides reliable reception capabilities within license-free frequency bands.

RF Receivers Procurement Notes

Verify that the specific part number matches the required 868 MHz frequency band and receiver-only functionality. Confirm that the SPI interface compatibility aligns with the target host controller's voltage levels and protocol settings. Ensure the supply voltage requirements of 1.8V to 3.6V are met by the system design. Check for any regional regulatory certifications if applicable to the deployment environment.

RF Receivers Selection Notes

Select this component when a dedicated receiver solution is required rather than a full transceiver. It is suitable for applications where cost reduction is prioritized over bidirectional communication capabilities. Ensure the application does not require transmission functions, as this model lacks a transmitter. Verify that the 868 MHz band is appropriate for the geographic region of operation.

RF Receivers Part Context

This module belongs to the RFM65W series from RF Solutions, which focuses on low-cost Sub-GHz receiver solutions. The series supports various ISM bands, including 433 MHz and 915 MHz, but this specific variant is tuned for 868 MHz. It serves as a complementary component to transceiver modules like the RFM95W, offering a specialized option for receive-only network architectures.
