HHM1516

Balun Overview

The HHM1516 is an RF balun manufactured by TDK Corporation, designed for high-frequency signal conversion applications. It operates within a frequency range of 1.71 GHz to 1.99 GHz, supporting standards such as LTE and Wi-Fi. The component provides impedance transformation from 50 Ohms on the unbalanced port to 200 Ohms on the balanced port. It is housed in a compact 0805 (2012 Metric) surface-mount package, facilitating integration into space-constrained mobile devices and wireless infrastructure.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion for RF circuits
• Supports wideband operation across cellular and wireless LAN frequencies
• Utilizes a compact surface-mount package for automated assembly

Balun Applications

• LTE modem modules
• Wi-Fi integrated circuits
• Mobile phone RF front-ends

Balun Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with TDK or authorized distributors before procurement. Ensure the ordering part number matches the required impedance and package dimensions. Confirm that the supplier provides traceability documentation to guarantee component authenticity and prevent counterfeit risks in critical RF designs.

Balun Selection Notes

Select this component when a 50-ohm single-ended interface must connect to a 200-ohm differential balanced line within the 1.71–1.99 GHz band. Evaluate insertion loss and return loss specifications against system requirements. Consider the thermal characteristics and soldering profile compatibility with the 0805 footprint during PCB layout and manufacturing processes.

Balun Part Context

This device belongs to TDK's portfolio of passive RF components, specifically baluns used for impedance matching and signal integrity. It complements other RF solutions like filters and inductors, enabling efficient transmission and reception of radio frequency signals in modern communication hardware without requiring complex discrete transformer networks.

Balun Replacement Considerations

Consult official TDK documentation for direct cross-reference part numbers. Verify that any substitute maintains identical impedance ratios, frequency coverage, and physical package dimensions to ensure circuit compatibility.
