RF1353C

Overview

The Murata Electronics RF1353C is a Surface Acoustic Wave (SAW) bandpass filter designed for signal conditioning in wireless applications. It operates at a center frequency of 345 MHz with a bandwidth of 430 kHz. The component features a 50-ohm impedance and supports a maximum voltage rating of 30 V. It exhibits an insertion loss of 4.5 dB and is housed in an SM-5050-8, 8-pin SMD package. The device functions within a temperature range of -10°C to +70°C.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise signal filtering
• Provides defined bandpass characteristics centered at 345 MHz
• Designed for compact surface-mount integration

Applications

• Wireless communication systems
• RF signal conditioning circuits
• Frequency selection modules

Procurement Notes

Verify the specific manufacturer designation, as sources indicate both RFMI and Murata Electronics associations. Confirm the lifecycle status, as some records list the part as obsolete. Ensure the datasheet matches the required 345 MHz center frequency and 430 kHz bandwidth specifications before procurement.

Selection Notes

Select this component when a fixed 345 MHz SAW filter is required for narrowband applications. Consider the 4.5 dB insertion loss and 430 kHz bandwidth against system sensitivity requirements. Verify compatibility with the SM-5050-8 footprint and 30 V voltage rating during circuit design.

Part Context

This component belongs to the category of RF signal conditioning devices, specifically SAW filters. It serves as a passive electronic component used to isolate specific frequency bands in radio frequency circuits. The SM-5050-8 package allows for automated surface-mount assembly in dense PCB layouts.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 345 MHz center frequency, 430 kHz bandwidth, and 50-ohm impedance specifications.
