D3C3742-5

RF Circulators And Isolators Overview

The D3C3742-5 is a three-port circulator manufactured by DiTom Microwave, designed for operation within the 3.7 GHz to 4.2 GHz frequency range. It features SMA female connectors and utilizes a module package configuration. The component supports an average forward power of 20 W, with a specified isolation of 23 dB and insertion loss of 0.3 dB. Voltage Standing Wave Ratio (VSWR) is rated at 1.2. This device is RoHS3 compliant and classified under ECCN EAR99.

RF Circulators And Isolators Feature Summary

• Provides directional signal routing via three-port circulation in the S-band frequency range
• Ensures high port-to-port isolation to minimize signal interference between ports
• Maintains low insertion loss for efficient signal transmission through the circuit
• Features robust SMA female connectors for secure interface integration

RF Circulators And Isolators Applications

• Transmitter-receiver switching in communication systems
• Duplexing applications in radar systems
• Signal routing in microwave test and measurement equipment

RF Circulators And Isolators Procurement Notes

Verify the specific suffix designation against official DiTom Microwave documentation to confirm connector type and performance tolerances. Ensure environmental compliance requirements align with project specifications, noting the RoHS3 status. Confirm that the SMA female interface matches the system board layout. Validate the 20 W power handling capability against actual operational thermal conditions.

RF Circulators And Isolators Selection Notes

Select this component when a fixed-frequency circulator is required for the 3.7–4.2 GHz band. Consider the 20 W average power limit and 23 dB isolation specification relative to system linearity requirements. Evaluate the module form factor for space constraints. Compare VSWR and insertion loss metrics against system budget constraints to ensure signal integrity.

RF Circulators And Isolators Part Context

The D3C3742-5 belongs to the D3C3742 series of connectorized ferrite circulators produced by DiTom Microwave. This series covers frequencies from 400 MHz to 43.5 GHz. The model specifically addresses S-band applications, offering a standardized solution for commercial and military microwave systems requiring reliable non-reciprocal signal flow.

RF Circulators And Isolators Replacement Considerations

The D3C3742-1 shares identical electrical specifications and physical dimensions, differing primarily in manufacturing batch or minor supplier-specific identifiers. Verify pinout compatibility and connector orientation before substitution. Cross-reference with other D3C3742 variants only if frequency ranges match exactly.
