RF3605D

Overview

The RF3605D is a Surface Acoustic Wave (SAW) bandpass filter manufactured by Murata Electronics, designed for TRC105 transceiver applications. It operates at a center frequency of 372.25 MHz with a bandwidth of 16 MHz. The device features an insertion loss of 1.5 dB and supports impedances of 50 Ohms and 150 Ohms. Rated for a maximum voltage of 5 V, it functions within a temperature range of -40°C to +85°C. The component is housed in an 8-SMD, no-lead package measuring 3.80mm x 3.80mm with a maximum height of 1.40mm.

• Optimized design for TRC105 transceiver integration
• Compact surface-mount packaging for board-level assembly

Applications

• TRC105 Transceiver systems
• RF signal conditioning circuits
• Bandpass filtering in wireless communication modules

Procurement Notes

Verify the specific manufacturer designation, as sources list both Murata Electronics and RFMi for this part number. Confirm the current product status, as some records indicate the component is obsolete or end-of-life. Ensure the datasheet matches the required impedance and frequency specifications before procurement. Check for any pending production change notices regarding assembly sites or material composition.

Selection Notes

Select this component when integrating with TRC105 transceivers requiring a 372.25 MHz center frequency. Ensure the circuit design accommodates the specified 50 Ohm and 150 Ohm impedance options. Verify that the operating environment stays within the -40°C to +85°C temperature range. Consider the 8-SMD package dimensions for PCB layout constraints.

Part Context

This SAW filter belongs to the RF series of components from Murata Electronics. It serves as a specialized passive component for radio frequency signal processing. The device is distinct from digital attenuators or cable assemblies also offered by the manufacturer. Its primary role is frequency selection in specific transceiver architectures.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the reported obsolete status, direct replacements may require redesigning the RF front-end or sourcing surplus inventory. Consult official manufacturer channels for potential last-time buy information or approved alternates.
