D3I4080-1

RF Circulators And Isolators Overview

The D3I4080-1 is a single-junction RF isolator manufactured by DiTom Microwave, designed for operation within the 4.00 to 8.00 GHz frequency range. This component features SMA female connectors and is housed in a module package with dimensions of 1 inch by 0.5 inch by 1 inch. It supports an average forward power of 30 W, providing 20 dB of isolation with an insertion loss of 0.4 dB and a VSWR of 1.25. The device is classified as a cryogenic isolator, indicating suitability for low-temperature environments, and is currently listed as obsolete.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission with high isolation characteristics across a broad microwave bandwidth.
• Engineered for cryogenic operational environments to maintain performance under extreme cold conditions.
• Utilizes a single-junction design to ensure stable impedance matching and minimal signal reflection.

RF Circulators And Isolators Applications

• Cryogenic receiver front-end protection
• Low-noise amplifier (LNA) isolation
• Microwave measurement systems requiring thermal stability

RF Circulators And Isolators Procurement Notes

Verify component availability status carefully as this model is marked as obsolete. Confirm specific connector gender requirements and physical mounting constraints against system specifications. Request updated datasheets directly from DiTom Microwave or authorized distributors to ensure compliance with current manufacturing standards and RoHS directives before finalizing procurement plans.

RF Circulators And Isolators Selection Notes

Select this component when cryogenic temperature operation is required alongside standard S-band to C-band isolation needs. Ensure the system can accommodate the specified 1-inch form factor. Compare performance metrics such as isolation and insertion loss against alternative models if cryogenic capability is not strictly necessary, as other variants may offer different operating temperature ranges.

RF Circulators And Isolators Part Context

This part belongs to the D3I4080 series of broadband and narrowband connectorized RF isolators produced by DiTom Microwave. The series includes various configurations such as the D3I4080-2 and D3I4080-3, which share similar frequency ranges but may differ in connector types or environmental ratings. The D3I4080-1 specifically denotes the cryogenic variant within this product line.

RF Circulators And Isolators Replacement Considerations

Public confirmed substitute part numbers are not available for this obsolete component. Consider evaluating the D3I4080-2 or D3I4080-3 for potential mechanical compatibility, though functional equivalence regarding cryogenic performance must be verified through official documentation.
