D4I1213-1

RF Circulators And Isolators Overview

The DiTom Microwave D4I1213-1 is an RF isolator designed for the K-band frequency range of 11.7 GHz to 12.7 GHz. It features SMA-FEMALE connectors and operates with a maximum average forward power of 10 W. Key electrical specifications include a typical insertion loss of 0.6 dB, an isolation level of 46 dB, and a voltage standing wave ratio (VSWR) of 1.2. The component is housed in a module format with SMA connectors and complies with RoHS3 standards.

RF Circulators And Isolators Feature Summary

• Provides high isolation performance of 46 dB within the specified frequency band
• Supports continuous average forward power handling up to 10 W
• Utilizes SMA-FEMALE connector configuration for standard interface compatibility

RF Circulators And Isolators Applications

• Microwave communication systems requiring signal directionality
• Test and measurement equipment interfaces
• Satellite ground station components

RF Circulators And Isolators Procurement Notes

Verify the specific suffix designation against official DiTom Microwave documentation to ensure correct connector orientation and mechanical tolerances. Confirm that the required operating temperature range aligns with the component's rated specifications before integration into final assemblies. Cross-reference the datasheet parameters with system requirements to validate isolation and VSWR performance at the target frequency.

RF Circulators And Isolators Selection Notes

Select this component when a dedicated isolator function is required rather than a circulator, as indicated by the part number structure. Ensure the system impedance matches the standard 50 Ohm characteristic implied by the SMA interface. Consider the thermal management capabilities relative to the 10 W power rating during continuous operation.

RF Circulators And Isolators Part Context

This model belongs to the D4I1213 series from DiTom Microwave, which focuses on microwave isolators. It is distinct from the D3C1213 circulator variant, which offers lower isolation but different port functionality. The series is engineered for stable performance in K-band applications where signal reflection protection is critical.
