HMC-XDB112

Overview

The HMC-XDB112 is a monolithic passive frequency doubler utilizing GaAs Heterojunction Bipolar Transistor (HBT) technology. It is designed as a die for high-frequency applications, specifically targeting cost-effective direct generation of higher frequencies from lower sources. The component operates within an input frequency range of 10 GHz to 15 GHz. It employs a passive architecture suitable for mass production scenarios requiring efficient frequency multiplication without active biasing requirements.

Feature Summary

• Monolithic integration using GaAs HBT technology for high-performance RF operation
• Passive design eliminates the need for external DC bias supplies
• Optimized for direct frequency doubling in high-volume manufacturing environments

Applications

• Direct up-conversion in satellite communication systems
• Frequency synthesis in radar transceivers
• Millimeter-wave signal generation for test and measurement equipment

Procurement Notes

Verify that the specific order corresponds to the bare die configuration rather than a packaged module or evaluation board. Confirm compatibility with GaAs HBT processing standards and ensure handling procedures account for the exposed pad and Ti/Au plating specifications defined in the official datasheet. Cross-reference the manufacturer part number to avoid confusion with similar active multiplier variants.

Selection Notes

Select this component when a passive, high-efficiency frequency doubling solution is required for the 10-15 GHz input band. It is appropriate for designs prioritizing low power consumption and simplified bias networks. Consider the GaAs HBT process characteristics for thermal management and impedance matching requirements inherent to passive MMIC dies.

Part Context
