RF1353D

Overview

The RF1353D is a Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi. It operates at a center frequency of 345 MHz with a passband range of 344 MHz to 346 MHz and a bandwidth of 430 kHz. The component features a nominal insertion loss of 4.5 dB and is designed for 50 Ohm impedance systems. It supports a maximum voltage rating of 30 V and functions within an operating temperature range of -10°C to +70°C. The device utilizes SMD/SMT termination and is housed in the SM-3838-6 package.

Feature Summary

• Provides precise signal conditioning through SAW technology for narrowband applications
• Designed for board mount integration using surface-mount device terminations
• Operates reliably within standard industrial temperature limits

Applications

• RF signal path filtering in communication transceivers
• Intermediate frequency stages in radio equipment
• Signal conditioning modules requiring 345 MHz selectivity

Procurement Notes

Verify the specific manufacturer designation, as sources indicate both RFMi and Murata Manufacturing Co., Ltd. associated with this part number. Confirm the package type matches the required PCB footprint, as documentation references the SM-3838-6 housing. Ensure the voltage rating and temperature range align with the target system environment before finalizing procurement orders.

Selection Notes

Select this component when a fixed 345 MHz center frequency with 430 kHz bandwidth is required. The 4.5 dB insertion loss specification suits applications where moderate signal attenuation is acceptable. The 50 Ohm impedance ensures compatibility with standard RF transmission lines. Consider the SM-3838-6 package dimensions during layout planning to ensure adequate clearance for surface mounting.

Part Context

This component belongs to the RF series of signal conditioning devices produced by RFMi. It is categorized under SAW filters, which utilize acoustic wave propagation for frequency selection. The product line targets wireless communication infrastructure and consumer electronics requiring stable bandpass characteristics at specific UHF frequencies.

Replacement Considerations

The RF1353C is documented as a variant within the same series. It shares identical electrical specifications including frequency, bandwidth, and impedance but utilizes the SM-5050-8 package. Verify mechanical compatibility if substituting between these two models.
