D3C3743

RF Circulators And Isolators Overview

The D3C3743 is a three-port RF circulator manufactured by DiTom Microwave, designed for operation within the 37 GHz to 43 GHz frequency range. It features Type-K female connectors on all ports and operates in a module package with dimensions of 0.5 inches by 0.5 inches by 0.7 inches. The component supports an average forward power of 5 W, offering an isolation of 14 dB and a maximum insertion loss of 1.2 dB. It maintains a voltage standing wave ratio (VSWR) of 1.35 and functions reliably between -20°C and +65°C.

RF Circulators And Isolators Feature Summary

• Provides directional signal flow control via a single junction design across the K-band spectrum
• Utilizes Type-K female connectors for standardized high-frequency interconnection
• Operates within a defined temperature range suitable for standard electronic environments

RF Circulators And Isolators Applications

• K-band radar systems requiring signal isolation
• Point-to-point microwave communication links
• Test and measurement instrumentation setups

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration required for your application, as suffixes such as -1 or Q-3 may indicate variations like Type-N interfaces. Confirm that the standard bulk packaging aligns with your handling procedures. Ensure the operating temperature limits meet your environmental requirements before finalizing the order.

RF Circulators And Isolators Selection Notes

Select this model when a fixed 37–43 GHz operational bandwidth is required. The Type-K interface dictates compatibility with mating cables and fixtures. Consider the 5 W power rating and 14 dB isolation metrics against system noise and leakage constraints. Verify physical space availability for the 0.5 x 0.5 x 0.7 inch module footprint.

RF Circulators And Isolators Part Context

This component belongs to the D3C3743 series of RF circulators from DiTom Microwave. Variants within this family, such as D3C3743Q-3 or D3C3743-1, share similar electrical performance but differ in connector types, specifically utilizing Type-N female interfaces in those instances. The base D3C3743 model retains the Type-K configuration.

RF Circulators And Isolators Replacement Considerations

Direct substitutes are not explicitly documented in the provided data. Models sharing the D3C3743 basic part number, including D3C3743Q-3 and D3C3743-1, offer alternative connector configurations rather than identical replacements.
