D3I9521N-1

RF Circulators And Isolators Overview

The D3I9521N-1 is a single-junction RF isolator manufactured by DiTom Microwave, operating within the frequency range of 950 MHz to 2.15 GHz. It features Type-N female connectors and supports an average forward power of 75 W. Key electrical specifications include 12 dB isolation, 1 dB insertion loss, and a VSWR of 1.65. The device operates between -10°C and +55°C, with physical dimensions of 2.8 in x 1 in x 2.8 in.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission to protect source components from reflected power
• Maintains stable impedance matching across the designated microwave frequency band
• Utilizes ferrite-based single junction technology for reliable RF performance

RF Circulators And Isolators Applications

• Transmitter output stages requiring protection against load mismatches
• Receiver input stages to prevent noise figure degradation from upstream reflections
• Bidirectional communication systems needing isolated signal paths
• Test and measurement setups requiring precise signal directionality

RF Circulators And Isolators Procurement Notes

Verify connector gender and interface type against system requirements before ordering. Confirm that the specified power handling and isolation levels meet the specific application's operational demands. Ensure environmental temperature ratings align with the intended deployment conditions. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

RF Circulators And Isolators Selection Notes

Select this component when a wide bandwidth covering 950 MHz to 2.15 GHz is required. Consider the 75 W power rating for high-power transmitter applications. Evaluate the physical footprint of 2.8 in x 1 in x 2.8 in for mechanical integration. Compare isolation and VSWR specs against alternative models if stricter performance thresholds are necessary.

RF Circulators And Isolators Part Context

This model belongs to the D3I9521N series of RF isolators from DiTom Microwave. It shares core design principles with other units in the family but differs in specific connector configurations and packaging options. The series targets general-purpose microwave applications requiring robust signal isolation.
