ECS-DSF400.0A-51-TR

Overview

The ECS-DSF400.0A-51-TR is a Surface Acoustic Wave (SAW) filter designed for intermediate frequency applications in GSM cellular systems. It operates at a nominal center frequency of 400 MHz with a maximum insertion loss of 6 dB. The component features an input impedance of 600 ohms in parallel with 90 nH. It is housed in an 8-SMD, no-lead package with a 5.0 x 5.0 mm footprint and supports extended temperature ranges while remaining RoHS compliant.

Feature Summary

Designed as an IF filter specifically for GSM cellular applications
Utilizes Surface Acoustic Wave technology for RF signal processing
Available in a compact SMD package suitable for surface mount assembly

Applications

GSM cellular communication systems
Intermediate frequency filtering in mobile devices
RF front-end modules requiring SAW filter solutions

Procurement Notes

Verify the complete part number including suffixes such as -TR for tape and reel configuration. Confirm that the 5.0 x 5.0 mm footprint matches your PCB design constraints. Ensure compatibility with the specified 400 MHz center frequency for your specific GSM application requirements before ordering.

Selection Notes

Select this component when a dedicated SAW filter is required for GSM IF stages. Consider the 6 dB insertion loss limit and 600 ohm input impedance for circuit matching. The extended temperature range makes it suitable for diverse environmental conditions compared to standard commercial grade parts.

Part Context

This device belongs to the ECS-DSF series of SAW filters manufactured by ECS Inc. International. These components are engineered for high-performance RF filtering in wireless communications. The series offers various center frequencies tailored to different cellular standards and band requirements.

Replacement Considerations

Check for direct substitutes within the ECS-DSF series that match the 400 MHz specification. Verify pinout compatibility and footprint dimensions against alternative SAW filters from other manufacturers if sourcing changes occur.
