Overview
The TDK DEA142450BT-3024A1 is a multilayer bandpass filter designed for 2.4GHz W-LAN and Bluetooth applications. It features a compact 1.4x1.1mm surface-mount package with five terminals. The device operates within the 2400-2500MHz frequency range, exhibiting a typical insertion loss of 0.97dB and a maximum of 1.10dB. Return loss reaches a typical value of 19dB with a minimum of 10dB in the passband. Attenuation specifications include 20-23dB at 50-960MHz and 10-12dB at 1710-1990MHz. The component maintains a nominal characteristic impedance of 50 ohms.
Feature Summary
- Engineered specifically for 2.4GHz wireless local area network and Bluetooth signal conditioning
- Utilizes low-loss LTCC technology to maintain signal integrity in compact designs
- Provides effective suppression of out-of-band interference across multiple frequency bands
Applications
- Wireless LAN modules operating in the 2.4GHz ISM band
- Bluetooth transceivers requiring RF front-end filtering
- Compact consumer electronics with limited PCB space
Procurement Notes
Verify the specific suffix code against official TDK documentation to confirm exact electrical tolerances and marking configurations. Ensure compatibility with standard reflow soldering profiles for LTCC components. Confirm RoHS compliance status through current manufacturer declarations prior to integration into final assemblies.
Selection Notes
Select this component when strict size constraints require a 1.4x1.1mm footprint for 2.4GHz filtering. Evaluate insertion loss requirements against the 0.97dB typical specification. Consider the 5-terminal SMD package for automated assembly processes. Verify impedance matching requirements align with the standard 50-ohm system design.
Part Context
This part belongs to the TDK DEA series of multilayer ceramic filters. These components are manufactured using Low-Temperature Co-fired Ceramic (LTCC) technology. The series targets high-volume mobile and IoT devices. The DEA142450BT-3024A1 represents a specific variant optimized for the 2.4GHz spectrum within this product line.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult TDK technical support or authorized distributors for validated cross-reference data before implementing alternative components.
