D3C9517S-1

RF Circulators And Isolators Overview

The D3C9517S-1 is a three-port RF circulator manufactured by DiTom Microwave, designed for operation within the 950 MHz to 1.7 GHz frequency range. This single-junction device utilizes SMA female connectors and operates at an average forward power of 75 W. Key electrical specifications include an isolation of 18 dB, insertion loss of 0.5 dB, and a voltage standing wave ratio (VSWR) of 1.3. The component functions within a temperature range of +10°C to +55°C and is housed in a module package with dimensions of 2.8 inches by 1 inch by 2.8 inches.

RF Circulators And Isolators Feature Summary

• Provides non-reciprocal signal routing across a wide UHF bandwidth using a single-junction design.
• Maintains high port-to-port isolation to prevent signal interference between connected components.
• Supports continuous wave power handling up to 75 watts for robust system performance.

RF Circulators And Isolators Applications

• Transmitter-receiver switching in communication systems
• Duplexing in radar systems
• Signal routing in multi-port antenna arrays

RF Circulators And Isolators Procurement Notes

Verify the specific suffix designation when ordering, as variations such as D3C9517S exist with potentially different packaging or connector configurations. Confirm that the required SMA female interface matches the system interconnect requirements. Ensure the operating environment remains within the specified temperature limits to maintain rated electrical performance and reliability standards.

RF Circulators And Isolators Selection Notes

Select this model when a wideband solution covering 950 MHz to 1.7 GHz is required. The 75 W power rating suits moderate power applications. Verify that the physical dimensions fit the available chassis space. Consider the 18 dB isolation level against system noise floor requirements. Ensure compatibility with SMA female connectors for seamless integration into existing test or production setups.

RF Circulators And Isolators Part Context

This component belongs to the DiTom Microwave D3C series of RF circulators. It shares the core frequency band and power handling characteristics with variants like the D3C9517S. The product line focuses on providing reliable non-reciprocal devices for UHF and microwave applications, utilizing standard connector interfaces for ease of integration into broader RF subsystems.

RF Circulators And Isolators Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate other DiTom models within the same frequency band for potential mechanical or electrical compatibility. Cross-reference isolation and VSWR specifications to ensure equivalent performance levels in the target application.
