D3I9517N-1

RF Circulators And Isolators Overview

The D3I9517N-1 is a single-junction RF isolator manufactured by DiTom Microwave, designed for operation within the 950 MHz to 1.7 GHz frequency range. This module features a Type-N female connector configuration and supports an average forward power rating of 75 W. Key electrical specifications include an isolation level of 18 dB, an insertion loss of 0.5 dB, and a voltage standing wave ratio (VSWR) of 1.3. The component operates reliably across a temperature range of -10°C to +55°C and complies with RoHS3 standards.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission with high reverse isolation to protect source components from reflected power.
• Engineered for robust performance in high-power RF applications with specified thermal stability.
• Utilizes a standard Type-N female interface for straightforward integration into existing coaxial systems.

RF Circulators And Isolators Applications

• RF transmitter output stages requiring signal directionality
• Receiver input protection against reflected energy
• Test and measurement equipment signal routing

RF Circulators And Isolators Procurement Notes

Verify that the specific part number matches the required frequency band and power handling capabilities for the intended application. Confirm connector type compatibility with system cabling. Check current availability status as lead times may vary. Ensure environmental ratings meet operational requirements. Review datasheet for detailed mechanical dimensions and mounting instructions prior to integration.

RF Circulators And Isolators Selection Notes

Select this model when a wideband isolator covering 950 MHz to 1.7 GHz is required. Consider the 75 W power rating and 18 dB isolation for adequate system protection. Evaluate the Type-N connector for interface compatibility. Compare VSWR and insertion loss metrics against system loss budgets. Assess physical dimensions for enclosure fitment.

RF Circulators And Isolators Part Context

This component belongs to the DiTom Microwave D3I9517 series of RF isolators. It is categorized under RF circulators and isolators within the manufacturer's portfolio. The product is distinct from circulator variants such as the D3C9517 series, serving specifically as a non-reciprocal two-port device rather than a three-port directional coupler.

RF Circulators And Isolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other DiTom Microwave models in the same frequency range if direct substitution is necessary.
