HHM1908A2

Balun Overview

The HHM1908A2 is a multilayer LTCC balun manufactured by TDK Corporation, designed for RF signal conversion. It operates within the frequency range of 4.9 GHz to 5.95 GHz. The component provides impedance transformation between an unbalanced port with a nominal impedance of 50 Ohms and a balanced port with a nominal impedance of 100 Ohms. It is housed in a compact 0402 (metric 1005) surface-mount package. This device facilitates efficient differential signaling in high-frequency applications.

Balun Feature Summary

• Integrates LTCC technology for stable RF performance
• Converts single-ended signals to differential signals
• Supports 50-ohm to 100-ohm impedance matching

Balun Applications

• RF front-end modules in wireless communication devices
• Differential amplifier input stages
• Antenna interface circuits

Balun Procurement Notes

Verify the specific datasheet version prior to procurement to ensure compliance with current technical specifications. Confirm that the 0402 package dimensions align with the target PCB layout requirements. Ensure the operating frequency range covers the intended application spectrum. Check for any updated safety or handling guidelines provided by the manufacturer.

Balun Selection Notes

Select this component when a compact solution is required for converting 50-ohm single-ended lines to 100-ohm differential pairs. It is suitable for designs operating between 4.9 GHz and 5.95 GHz. Consider the LTCC construction for thermal stability. Evaluate the return loss specifications against system requirements to ensure signal integrity.

Balun Part Context
