HHM1506

Balun Overview

The HHM1506 is a multilayer balun designed for RF applications, specifically targeting WCDMA systems. It operates within two distinct frequency ranges: 1.92 GHz to 1.98 GHz and 2.11 GHz to 2.17 GHz. The component provides an impedance transformation from 50 Ohms on the unbalanced side to 100 Ohms on the balanced side. It maintains a phase difference of 180 degrees with a tolerance of ±10 degrees. The device is housed in a compact 0805 surface-mount package.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion for RF circuits
• Supports dual frequency bands for flexible system integration
• Utilizes multilayer construction for reliable performance

Balun Applications

• WCDMA transceiver modules
• RF front-end circuitry
• Wireless communication devices

Balun Procurement Notes

Verify the specific datasheet revision and ordering suffix when sourcing. Confirm that the component status remains active for long-term supply chain stability. Ensure compatibility with standard SMT assembly processes for 0805 packages. Cross-reference electrical specifications against current design requirements to avoid mismatches in impedance or frequency response.

Balun Selection Notes

Select this component for designs requiring a 50-ohm to 100-ohm transformation in the specified RF bands. Consider the 0805 footprint constraints during PCB layout planning. Evaluate thermal management needs based on power handling capabilities defined in the official documentation. Ensure the phase accuracy meets the system's demodulation requirements.

Balun Part Context

This balun belongs to TDK's portfolio of passive RF components intended for wireless infrastructure and mobile devices. It addresses the need for compact, high-performance signal conditioning in modern communication standards. The product line emphasizes miniaturization while maintaining strict electrical tolerances for critical RF paths.

Balun Replacement Considerations

Consult official substitution guides for equivalent baluns with matching impedance ratios and frequency coverage. Verify pinout compatibility and mechanical dimensions before swapping. Ensure alternative parts meet the same phase difference and insertion loss specifications.
