HHM17152A1

Balun Overview

The TDK HHM17152A1 is a multilayer ceramic RF balun designed for balanced-to-unbalanced signal conversion. It operates within a frequency range of 698MHz to 894MHz, supporting applications in wireless communication systems. The component features a 50/100 Ohm impedance configuration and maintains a phase difference of 180° ±10°. Insertion loss is specified at a maximum of 1.2dB. Housed in a compact 0603 (1608 metric) surface-mount package, it ensures reliable performance in space-constrained designs while adhering to RoHS3 environmental standards.

Balun Feature Summary

• Provides balanced-to-unbalanced signal transformation for RF circuits
• Optimized for operation within the 698MHz to 894MHz frequency band
• Ensures precise 180-degree phase difference with low insertion loss
• Utilizes a compact 0603 surface-mount ceramic construction

Balun Applications

• Wireless local area network (WLAN) transceivers
• Bluetooth module signal processing
• Mobile device RF front-end interfaces
• IoT sensor node connectivity circuits

Balun Procurement Notes

Verify the specific ordering suffix to confirm packaging type, as DigiKey lists both tape and reel (TR) and cut tape (CT) variants under distinct part numbers. Confirm the manufacturer part status remains active or last-time-buy before finalizing procurement plans. Ensure compatibility with standard surface-mount reflow soldering profiles during assembly integration.

Balun Selection Notes

Select this component when designing circuits requiring conversion between 50-ohm unbalanced and 100-ohm balanced lines within the specified sub-GHz frequency range. Consider the 0603 footprint constraints and the maximum 1.2dB insertion loss tolerance against system link budget requirements. Evaluate thermal management capabilities inherent to the multilayer ceramic structure for high-density PCB layouts.

Balun Part Context

This component belongs to the TDK HHM series of passive RF devices. It serves as a critical interface element in modern wireless connectivity solutions, enabling efficient signal transfer between differential and single-ended paths. The design supports the miniaturization trends in consumer electronics and industrial IoT hardware by providing robust performance in a minimal physical envelope.

Balun Replacement Considerations

The HHM17144A1 is a documented substitute offering similar functionality but operating in the 791MHz to 960MHz range. Verify impedance matching and frequency overlap requirements before substitution. Ensure the replacement maintains the required 0603 package dimensions and pin configuration for direct board compatibility.
