DEA165550BT-2230C2-H

Overview

The DEA165550BT-2230C2-H is a multilayer LTCC bandpass filter manufactured by TDK. It operates within the 5150 MHz to 5950 MHz frequency range, centered at 5550 MHz with an 800 MHz bandwidth. The component features a 50 Ohm impedance and 0.9 dB insertion loss. It utilizes a 0603 (1.60mm x 0.80mm) surface-mount package with a maximum height of 0.60 mm. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for compact signal conditioning
• Provides precise bandpass filtering in the 5.15 GHz to 5.95 GHz spectrum
• Designed for high-reliability surface-mount integration

Applications

• Wireless LAN systems operating in the 5 GHz band
• Wi-Fi connectivity modules
• RF front-end signal conditioning

Procurement Notes

Verify the specific suffix 'H' against official TDK documentation to confirm compliance with RoHS3 standards and lead-free requirements. Ensure the ordering part number matches the exact electrical specifications required for your design, as minor variations exist within the DEA series. Confirm package dimensions align with your PCB land pattern guidelines before finalizing procurement.

Selection Notes

Select this component when a compact 0603 footprint is required for 5 GHz RF applications. The 0.9 dB insertion loss offers efficient signal transmission compared to larger filters. Verify that the 5150-5950 MHz passband aligns with your regulatory frequency allocations. Consider thermal management capabilities within the specified -40°C to +85°C operational range during system design.

Part Context

This device belongs to the TDK DEA series of LTCC bandpass filters. These components are engineered for high performance in wireless communication devices. The series provides various center frequencies and bandwidths to suit different RF standards. The DEA165550BT-2230C2-H specifically targets the 5 GHz ISM/U-NII bands common in modern networking equipment.

Replacement Considerations

Consult TDK's official substitution guide for compatible alternatives. Cross-reference center frequency and bandwidth tolerances carefully. Verify that any substitute maintains the same 0603 footprint and 50 Ohm impedance to ensure board compatibility without redesign.
