RF3619D

Overview

The RF3619D is a Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi. It operates at a center frequency of 404.0 MHz with a specified frequency range extending from 0 Hz to 3 GHz. The component features a voltage rating of 3 V and an insertion loss of 1.7 dB. Designed for board mounting, it utilizes SMD/SMT termination types and is housed in a compact 8-SMD, No Lead package measuring 3.8 mm x 3.8 mm x 1.4 mm. The device supports an operating temperature range from +5°C to +40°C and belongs to the SF series.

Feature Summary

• Provides signal conditioning through SAW technology for precise frequency selection
• Optimized for low insertion loss to maintain signal integrity
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• Frequency control elements in transmitters
• RF signal conditioning circuits
• Wireless communication systems requiring 404 MHz filtering

Procurement Notes

Verify the specific datasheet version for the RF3619D to confirm exact electrical tolerances and thermal specifications before integration. Ensure compatibility with standard reflow soldering profiles, typically peaking at 260°C, to prevent component damage during assembly. Cross-reference the manufacturer's latest documentation for any updates regarding RoHS compliance status or recommended land pattern designs to ensure reliable manufacturing outcomes.

Selection Notes

Select the RF3619D when a dedicated SAW filter is required for the 404 MHz band within wireless applications. Consider its 3.8 mm x 3.8 mm footprint for dense circuit designs. Evaluate the 1.7 dB insertion loss against system link budget requirements. Confirm that the +5°C to +40°C operating range aligns with the environmental conditions of the final deployment scenario.
