D4I9525

RF Circulators And Isolators Overview

The D4I9525 is an RF isolator manufactured by DiTom Microwave, designed for operation within the 950 MHz to 1.225 GHz frequency range. It features SMA female connectors and supports an average forward power of 250 W. Key electrical specifications include a minimum isolation of 40 dB, insertion loss of 0.8 dB, and a VSWR of 1.25. The component operates between -20°C and +65°C, housed in a module package with dimensions of 1.25 inches.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission with high reverse isolation to protect source components from reflected power.
• Engineered for thermal vacuum environments, supporting operation at pressures below 5x10^-5 torr.

RF Circulators And Isolators Applications

• Satellite communication systems requiring reliable RF signal routing.
• Ground station equipment operating within the specified microwave frequency band.
• Test and measurement setups demanding low insertion loss and high isolation.

RF Circulators And Isolators Procurement Notes

Verify the specific datasheet version for the D4I9525 to confirm connector gender and mechanical dimensions match system requirements. Ensure environmental ratings align with operational conditions, particularly regarding thermal vacuum compatibility if applicable. Cross-reference manufacturer part numbers to avoid confusion with similar models like D3I9525N or D4C9525-1.

RF Circulators And Isolators Selection Notes

Select this model when a single-junction isolator is required for frequencies up to 1.225 GHz. Consider the 250 W power handling capability for high-power applications. Verify that SMA female interfaces are compatible with existing cabling infrastructure. Evaluate the 0.8 dB insertion loss against system budget constraints.

RF Circulators And Isolators Part Context
