D4C4450-4

RF Circulators And Isolators Overview

The D4C4450-4 is a coaxial circulator manufactured by DiTom Microwave, designed for operation within the 4.4 GHz to 5.0 GHz frequency range. It features SMA female connectors and is housed in a module package with dimensions of 1 inch by 0.5 inch by 1 inch. The component supports an average forward power of 20 W, providing 23 dB of isolation. Key electrical specifications include a maximum insertion loss of 0.3 dB and a Voltage Standing Wave Ratio (VSWR) of 1.15. It operates between -30°C and +60°C and complies with RoHS3 standards.

RF Circulators And Isolators Feature Summary

• Provides directional signal flow control via three-port circulation
• Maintains low signal attenuation through minimal insertion loss
• Ensures port-to-port isolation to prevent signal reflection
• Utilizes robust SMA female interface for secure connection

RF Circulators And Isolators Applications

• Transmitter output stages for signal protection
• Receiver input stages for noise reduction
• Duplexer configurations in communication systems
• Test and measurement equipment RF chains

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration and power rating against system requirements before ordering. Confirm that the operating temperature range aligns with the intended environment. Check for RoHS3 compliance if environmental regulations apply. Ensure the SMA female interface matches the mating cable or fixture. Validate the isolation and VSWR specifications meet the application's performance thresholds.

RF Circulators And Isolators Selection Notes

Select this component when a 4.4 to 5.0 GHz frequency range is required. Choose based on the need for 20 W power handling capability. Consider the SMA female interface for compatibility. Evaluate the 23 dB isolation level for system noise floor requirements. Assess the 0.3 dB insertion loss impact on overall link budget.

RF Circulators And Isolators Part Context

This model belongs to the D4C4450 series of coaxial circulators from DiTom Microwave. It shares the core frequency band and structural design with other variants in the family but differs in connector type and specific electrical tolerances. The series targets applications requiring reliable signal directionality in the specified microwave range.

RF Circulators And Isolators Replacement Considerations

Direct substitutes may include other models within the D4C4450 series from DiTom Microwave that match the 4.4-5.0 GHz range and SMA interface. Cross-brand replacements must verify identical frequency, power, and connector specifications.
