RF3396D

Overview

The RF3396D is a Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi. It operates at a center frequency of 434.42 MHz with a bandwidth ranging from 434.22 MHz to 434.62 MHz. The component features an insertion loss of 2.7 dB and supports a voltage rating of 12 V. It utilizes a 50 Ohm impedance interface and is housed in an SM-3838-8 surface-mount package. The device is designed for signal conditioning applications within the specified frequency range.

Feature Summary

• Provides precise signal filtering at 434.42 MHz using SAW technology
• Supports remote control applications with defined bandwidth constraints
• Utilizes surface-mount packaging for board integration

Applications

• Remote control systems
• Signal conditioning circuits
• RF front-end filtering

Procurement Notes

Verify the specific datasheet version for the RF3396D to confirm exact electrical tolerances and thermal characteristics. Ensure compatibility with the target PCB footprint, specifically the SM-3838-8 package dimensions. Confirm that the 12 V voltage rating aligns with the system power supply requirements. Check for any RoHS compliance documentation if required by the end product regulations.

Selection Notes

Select this component when a narrowband filter is required for the 434 MHz ISM band or similar remote control frequencies. The 50 Ohm impedance matches standard RF transmission lines. Consider the 2.7 dB insertion loss impact on overall link budget. The SM-3838-8 package offers a compact solution for space-constrained designs requiring SAW filter performance.

Part Context

The RF3396D belongs to the RFMi SAW filter portfolio, which includes various resonators and filters based on SAW, Xtal, and Ceramic technologies. These components are engineered for digital and wireless communication devices. The manufacturer focuses on providing frequency control elements for transmitters and signal conditioning modules.

Replacement Considerations

No direct public substitute part numbers are confirmed for the RF3396D in the provided source material. Verify compatibility with alternative SAW filters only if they match the 434.42 MHz center frequency, 50 Ohm impedance, and SM-3838-8 package dimensions exactly.
