Key electrical specifications include an insertion loss of 0.4 dB, an isolation rating of 20 dB, and a VSWR of 1.25. The physical dimensions are 1.25 in x 0.73 in x 1.25 in. It functions within a temperature range of -20°C to +65°C.

RF Circulators And Isolators Feature Summary

• Provides signal isolation with 20 dB attenuation in the reverse direction
• Supports high average forward power handling up to 250 W
• Utilizes SMA-FEMALE connectors for interface compatibility
• Designed as a single junction thermal vacuum coaxial ferrite device

RF Circulators And Isolators Applications

• RF systems requiring directional signal flow control
• Protection of sensitive RF sources from reflected power
• Applications operating within the 950 MHz to 1.225 GHz band
• Environments requiring operation at temperatures between -20°C and +65°C

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration and power ratings against system requirements before procurement. Confirm that the SMA-FEMALE interface matches the mating components in the assembly. Ensure the operating environment stays within the specified -20°C to +65°C temperature range. Check RoHS compliance status if environmental regulations apply to the final product integration.

RF Circulators And Isolators Selection Notes

Select this model when a single junction isolator is required for the 950 MHz to 1.225 GHz frequency range. Consider the 250 W power handling capability for high-power applications. Ensure the 0.4 dB insertion loss meets system efficiency targets. Verify that the 1.25 in x 0.73 in x 1.25 in form factor fits the available space constraints.

RF Circulators And Isolators Part Context

This component belongs to the D3I9525 series of RF isolators from DiTom Microwave. It is part of a family of thermal vacuum coaxial ferrite devices designed for robust performance. The series includes variants with different connector types, such as the D3I9525N. These components are categorized under RF Circulators and Isolators.

RF Circulators And Isolators Replacement Considerations

The D3I9525N is a related variant within the same series, differing primarily in connector type (Female-Female vs Male-Female). Both share the same frequency range and core specifications. Direct substitution requires verifying connector compatibility with the existing circuit layout.
