RF1407D

Overview

The Murata Electronics RF1407D is a Surface Acoustic Wave (SAW) filter designed for front-end selectivity in 868.6 MHz receivers. It operates within a frequency range of 868.21 MHz to 868.99 MHz with a bandwidth of 960 kHz. The component features an insertion loss of 3 dB and an impedance of 117 Ohms. Rated for 12 V, it supports SMD/SMT board mounting in an SM-3838-8 package. The device functions between -45°C and +90°C and holds AEC-Q200 qualification.

Feature Summary

• Provides front-end signal selectivity for remote control applications
• Compact surface-mount design for efficient PCB integration
• Low-loss performance optimized for receiver sensitivity

Applications

• 868.6 MHz remote control receivers
• Industrial, Scientific, and Medical (ISM) band equipment
• Wireless sensor networks operating in the 868 MHz region

Procurement Notes

Verify the manufacturer designation carefully, as some listings attribute this part to RFMi while official datasheets identify Murata Electronics North America. Confirm the specific suffix or revision code matches your design requirements. Ensure the SM-3838-8 package footprint aligns with your PCB layout. Check for AEC-Q200 certification if automotive compliance is required for your specific application context.

Selection Notes

Select this component when designing for the European 868 MHz ISM band. The 117 Ohm impedance requires matching network considerations distinct from standard 50 Ohm systems. The wide operating temperature range suits industrial environments. Verify that the 3 dB insertion loss meets the link budget requirements for your specific receiver sensitivity targets.

Part Context

This SAW filter belongs to the RF series of signal conditioning components. It serves as a critical interface element between the antenna and the low-noise amplifier in superheterodyne or direct-conversion receiver architectures. Its primary role is rejecting out-of-band interference while passing the desired 868.6 MHz signal with minimal attenuation.
