HHM1520A2

Balun Overview

The HHM1520A2 is a multilayer balun transformer manufactured by TDK Corporation, designed for RF applications in the 2.3GHz to 2.5GHz frequency range. It converts between unbalanced and balanced signals with nominal impedances of 50 Ohms on the unbalanced port and 100 Ohms on the balanced port. The component is housed in an 0805 (2012 metric) surface-mount package, suitable for automated assembly via tape and reel. This device supports wireless LAN and Bluetooth functionalities within the specified band.

Balun Feature Summary

• Multilayer construction for compact integration
• Balanced-to-unbalanced signal conversion
• Optimized for 2.4GHz ISM band operations

Balun Applications

• Wireless LAN modules
• Bluetooth transceivers
• RF front-end circuits

Balun Procurement Notes

Verify part status as obsolete before procurement planning. Confirm compatibility with existing design layouts due to potential supply chain discontinuation. Ensure alternative sourcing strategies are established if long-term production support is required for the end product.

Balun Selection Notes

Select this component when a 50-ohm to 100-ohm impedance transformation is required in a 0805 footprint. Validate that the operating frequency aligns with the 2.3GHz to 2.5GHz specification. Consider the obsolete status when designing for new products requiring long lifecycle support.

Balun Part Context

Part of the HHM series of multilayer baluns from TDK Electronics. Designed specifically for high-frequency RF signal processing. Shares family characteristics with other HHM models but differs in specific impedance ratios and frequency tuning for targeted wireless standards.

Balun Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-compatible alternatives should be identified through current manufacturer catalogs or authorized distributor cross-reference tools.
