HHM1918A2

Balun Overview

The HHM1918A2 is a multilayer balun manufactured by TDK Corporation using low-temperature co-fired ceramic (LTCC) technology. It operates within a frequency range of 2.3 GHz to 2.7 GHz, providing impedance transformation between 50 Ohms and 100 Ohms. The component is housed in a compact 0402 surface-mount package, designed for applications requiring low insertion loss and low latency performance.

Balun Feature Summary

• Utilizes LTCC technology for enhanced signal integrity
• Provides balanced-to-unbalanced conversion
• Compact 0402 surface-mount footprint

Balun Applications

• RF front-end modules
• Wireless communication devices
• Balanced antenna interfaces

Balun Procurement Notes

Verify the specific manufacturer designation, as sources list both TDK Corporation and TDK Electronics. Confirm the package type matches the required 0402 form factor. Ensure the frequency range specification aligns with the 2.3 GHz to 2.7 GHz operational requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Balun Selection Notes

Select this component when a small form factor is critical for PCB layout constraints. The LTCC construction offers advantages in thermal stability and signal performance compared to other technologies. Consider the impedance matching requirements of the circuit, specifically the transition between 50 Ohm and 100 Ohm lines, to ensure proper system integration.

Balun Part Context

This part belongs to the family of RF baluns produced by TDK. These components are engineered for high-frequency applications where size and performance are paramount. The use of LTCC allows for precise impedance control and reliable operation in demanding electronic environments.

Balun Replacement Considerations

The HHM1917A5 is a related part number from the same manufacturer series. Verify compatibility regarding frequency range and impedance specifications before substitution.
