HHM1711E1

Balun Overview

The HHM1711E1 is a surface-mount RF balun manufactured by TDK Corporation, designed for wireless applications operating within the 2.3GHz to 2.7GHz frequency range. This component facilitates signal conversion between 50Ω unbalanced and 100Ω balanced circuits. It utilizes a compact 0603 (1608 Metric) package with a 6-pad configuration, ensuring efficient integration into high-frequency circuit boards while maintaining signal integrity across the specified bandwidth.

Balun Feature Summary

• Enables efficient impedance transformation between 50-ohm unbalanced and 100-ohm balanced RF paths
• Optimized for stable performance in wireless communication systems within the designated frequency band
• Utilizes a low-profile surface-mount footprint suitable for dense PCB layouts

Balun Applications

• Wireless local area network (WLAN) modules
• Bluetooth low energy (BLE) transceivers
• Zigbee and other IEEE 802.15.4 based devices

Balun Procurement Notes

Verify current availability status as the manufacturer has indicated this component is scheduled for obsolescence. Confirm that the final procurement order explicitly references the full part number HHM1711E1 to ensure correct identification of the specific 2.3GHz to 2.7GHz variant. Request updated lifecycle documentation from authorized distributors prior to placing orders to mitigate supply chain risks associated with end-of-life products.

Balun Selection Notes

Select this component when designing circuits requiring a transition from standard 50-ohm transmission lines to 100-ohm differential balanced pairs. Ensure the design environment supports operation within the 2.3GHz to 2.7GHz spectrum. The 0603 package size dictates strict adherence to recommended pad layout dimensions to maintain electrical performance and mechanical reliability during assembly processes.

Balun Part Context

This balun belongs to the HHM series of RF components produced by TDK Corporation. The series focuses on providing reliable signal conversion solutions for modern wireless technologies. The HHM1711E1 specifically addresses the needs of compact consumer electronics requiring precise impedance matching in the sub-GHz and 2.4GHz ISM bands.

Balun Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the scheduled obsolescence status, engineers should evaluate alternative baluns from the same or competing manufacturers that offer compatible electrical specifications and pin configurations for direct replacement.
