HHM15107A2

Balun Overview

The HHM15107A2 is a multilayer RF balun manufactured by TDK Corporation, designed for operation within the 2.3GHz to 2.7GHz frequency range. It provides impedance transformation between unbalanced and balanced ports, both nominally rated at 50 ohms. The component utilizes a surface-mount package in the 0805 (2012 metric) footprint with six printed circuit board pads. Key electrical specifications include a maximum insertion loss of 1.2dB, a minimum return loss of 9dB, and a phase difference of 177.5 degrees. The device is RoHS compliant and classified under ECCN EAR99.

Balun Feature Summary

• Provides conversion between unbalanced and balanced RF signals
• Maintains nominal 50-ohm impedance on both ports
• Engineered for high-frequency wireless applications
• Utilizes compact multilayer ceramic construction

Balun Applications

• RF front-end modules in wireless communication devices
• Antenna interface circuits requiring signal balancing
• High-frequency signal processing systems

Balun Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the received parts match the specified 0805 package dimensions and pin configuration. Check for physical damage to the ceramic body and solder pads prior to assembly. Ensure storage conditions comply with moisture sensitivity level requirements to maintain solderability and electrical performance during reflow processes.

Balun Selection Notes

Select this component when designing circuits operating specifically within the 2.3GHz to 2.7GHz band. Ensure the design accommodates the 0805 footprint and six-pad layout constraints. Consider the specified insertion loss and return loss limits to verify system-level performance requirements. Verify compatibility with the target impedance matching network for optimal signal transfer efficiency.

Balun Part Context

This part belongs to the HHM series of multilayer baluns produced by TDK Corporation. These components are engineered for surface-mount integration into high-frequency electronic assemblies. The series supports various impedance configurations tailored for specific RF application needs.

Balun Replacement Considerations

The datasheet indicates the part status is not recommended for new designs. Evaluate alternative balun components from the same manufacturer or other suppliers that offer updated availability and comparable electrical characteristics for the 2.3GHz to 2.7GHz frequency range.
