D3C5771

RF Circulators And Isolators Overview

The DiTom Microwave D3C5771 is a three-port RF circulator designed for the 5.7 GHz to 7.1 GHz frequency range. It features SMA female connectors on all ports and operates within a temperature range of -30°C to +65°C. Key electrical specifications include an average forward power rating of 20 W, insertion loss of 0.5 dB, isolation of 18 dB, and a VSWR of 1.3. The component utilizes a single junction design and is housed in a module package measuring 0.62 inches by 0.5 inches by 0.78 inches.

RF Circulators And Isolators Feature Summary

• Provides directional signal flow control via a three-port architecture with SMA female interfaces.
• Maintains low insertion loss and high isolation characteristics across the specified microwave band.
• Supports continuous wave operation with a rated average forward power capacity.

RF Circulators And Isolators Applications

• RF wireless communication systems operating in the 5.7–7.1 GHz band
• Transmitter-receiver signal separation in radar architectures
• Antenna switching networks requiring unidirectional power transfer

RF Circulators And Isolators Procurement Notes

Verify the specific ordering suffix required for your connector configuration, as variants such as D3C5771-1 or D3C5771-5 exist within the same family. Confirm that the selected part matches the necessary SMA female interface requirements. Check current availability status, as lead times may vary based on manufacturer stock levels. Ensure compliance with RoHS3 standards if environmental regulations apply to your project.

RF Circulators And Isolators Selection Notes

Select this component when a fixed-frequency circulator is needed for the 5.7–7.1 GHz spectrum. Evaluate the 20 W power handling against your system's peak and average power levels. Consider the physical dimensions of 0.62 x 0.5 x 0.78 inches for PCB layout constraints. Verify thermal management capabilities given the -30°C to +65°C operating range.

RF Circulators And Isolators Part Context

The D3C5771 belongs to the D3C5771 series of RF circulators manufactured by DiTom Microwave. This series targets applications requiring reliable signal routing in microwave frequencies. The base model defines the core electrical performance, while suffixes typically denote specific packaging or connector variations. It serves as a fundamental passive component in RF front-end designs.

RF Circulators And Isolators Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Variants like D3C5771-1 share identical electrical parameters but may differ in packaging or suffix codes. Cross-reference mechanical dimensions and connector types carefully when evaluating alternative manufacturers' components for equivalent performance.

RF Circulators And Isolators FAQ

What is the isolation specification of the D3C5771?
