FD25

Overview

The FD25 is a passive bridge diode frequency doubler manufactured by MACOM Technology Solutions. It operates within a frequency range of 10MHz to 4.8GHz. The device utilizes Schottky diodes for signal processing and is designed for general-purpose RF applications. It is available in surface-mount packages including FP-2 and TO-8 configurations, supporting integration into various electronic systems requiring frequency multiplication.

Feature Summary

• Passive bridge diode architecture utilizing Schottky technology
• General-purpose frequency doubling capability across wide bandwidth
• Designed for robust performance in military and commercial environments

Applications

• Military equipment systems
• Commercial test equipment
• General RF signal conditioning

Procurement Notes

Verify the specific package variant required, as the FD25 family includes distinct physical footprints such as FP-2 and TO-8. Confirm that the selected component matches the intended circuit layout constraints. Ensure compatibility with existing supply chain requirements regarding manufacturer standard packaging quantities and lead times before finalizing procurement orders.

Selection Notes

Select this component when a passive frequency doubling solution is required for frequencies between 10MHz and 4.8GHz. Consider the physical package constraints, specifically choosing between FP-2 or TO-8 formats based on board space and mounting preferences. Validate that the passive nature of the device aligns with the system's power budget and signal integrity requirements.

Part Context

The FD25 belongs to a broader family of frequency doublers from MACOM, which includes variants like FD25C, FD25E, and SFD25. These components share similar functional principles but may differ in packaging or specific manufacturing revisions. The FD25 serves as a foundational model for passive Schottky-based frequency multiplication in RF design.

Replacement Considerations

Direct substitutes include FD25C, FD25E, and SFD25, provided the package type (FP-2 or TO-8) matches the original design. Verify pinout compatibility and ensure that any cross-model substitution does not alter the electrical performance specifications required by the application.
