Overview
The Murata Electronics RF2040E is a surface-mount SAW bandpass filter designed for narrowband receiver front ends. It operates at a center frequency of 915 MHz with a bandwidth of 31 MHz. The device features an impedance configuration of 50 Ohms and 130 Ohms, supporting a voltage rating of 5 V. Packaged in an SM3030-8 SMD/SMT form factor, it has a maximum height of 1.40 mm (0.055 inches). This component serves as a signal conditioning element within RF circuits.
Feature Summary
- Narrowband filtering capability centered at 915 MHz
- Surface-mount construction for automated assembly
- Integrated signal conditioning for receiver front ends
Applications
- RF receiver front end signal conditioning
- Narrowband communication systems
- 915 MHz ISM band applications
Procurement Notes
Verify the specific package designation SM3030-8 against your PCB footprint requirements. Confirm that the 5 V voltage rating aligns with your circuit's operational limits. Ensure compatibility with standard SMD/SMT reflow processes. Cross-reference the 50 Ohm and 130 Ohm impedance values with your system design to prevent signal mismatch issues during integration.
Selection Notes
Select this component when a compact SAW filter is required for 915 MHz narrowband applications. The low profile of 1.40 mm suits space-constrained designs. Consider the specific impedance matching requirements of 50 and 130 Ohms for optimal performance. Validate that the surface-mount termination style meets your manufacturing capabilities.
Part Context
The RF2040E belongs to Murata's SAW filter family, specifically engineered for RF signal processing. It functions as a bandpass filter within the broader category of signal conditioning components. The device supports high-frequency operations typical of industrial, scientific, and medical radio bands, providing essential spectral purity for downstream receiver stages.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify exact electrical parameters and mechanical dimensions before considering alternative sources or generic equivalents.
