D4C1218-1

RF Circulators And Isolators Overview

The D4C1218-1 is a circulator manufactured by DiTom Microwave, designed for operation within the 12.00 GHz to 18.00 GHz frequency range. This component features SMA-FEMALE connectors and utilizes a module package configuration. It supports an average forward power of 5 W while maintaining a voltage standing wave ratio (VSWR) of 1.25. The device provides an isolation level of 20 dB with an insertion loss of 0.5 dB. It complies with RoHS3 standards and carries an ECCN classification of EAR99.

RF Circulators And Isolators Feature Summary

• Provides directional signal routing capability across the K-band spectrum
• Integrates SMA-FEMALE interfaces for standardized interconnection
• Constructed in a compact module format suitable for integration

RF Circulators And Isolators Applications

• K-band radar systems requiring signal directionality
• Microwave communication links utilizing the 12-18 GHz band
• Test and measurement instrumentation setups

RF Circulators And Isolators Procurement Notes

Verify the specific suffix designation against project requirements to ensure compatibility with system interface specifications. Confirm that the 5 W power rating aligns with operational thermal limits. Check current availability status as lead times may vary based on manufacturer schedules. Ensure compliance with export control classifications relevant to the deployment region.

RF Circulators And Isolators Selection Notes

Select this component when a circulator is required for the 12-18 GHz range with moderate isolation needs. The 20 dB isolation specification suits applications where strict signal separation is not critical. Consider the SMA-FEMALE connector type for board layout compatibility. Evaluate the 0.5 dB insertion loss impact on overall system gain budgets before finalizing the design.

RF Circulators And Isolators Part Context

This part belongs to the D4C1218 series of microwave circulators from DiTom Microwave. Variants within this series typically share the same frequency coverage and physical dimensions but may differ in isolation performance or connector configurations. The D4C1218-1 represents a specific configuration optimized for general-purpose K-band applications.

RF Circulators And Isolators Replacement Considerations

The D3C1218-4 serves as a functional alternative within the same product family, offering higher isolation at 22 dB and lower insertion loss of 0.45 dB while maintaining identical frequency and power ratings.
