D3I0555-1

RF Circulators And Isolators Overview

The D3I0555-1 is a single-junction RF isolator manufactured by DiTom Microwave, designed for operation within the 500 MHz to 550 MHz frequency range. It features SMA-FEMALE connectors and supports an average forward power of 300 W. Key electrical specifications include 20 dB isolation, 0.4 dB insertion loss, and a VSWR of 1.25. The component is housed in a module with SMA connectors, complies with RoHS3 standards, and has a moisture sensitivity level of 1.

RF Circulators And Isolators Feature Summary

• Provides directional signal transmission with high isolation capabilities
• Supports high average forward power handling for robust performance
• Utilizes single-junction design for efficient RF signal management

RF Circulators And Isolators Applications

• Quantum computing systems
• RF measurement equipment
• Microwave communication links

RF Circulators And Isolators Procurement Notes

Verify the specific part number D3I0555-1 against official DiTom Microwave documentation to confirm SMA-FEMALE connector configuration and 20 dB isolation rating. Ensure compatibility with system requirements for the 500 MHz to 550 MHz band and 300 W power handling. Confirm RoHS3 compliance status prior to integration into sensitive electronic assemblies.

RF Circulators And Isolators Selection Notes

Select this isolator when precise isolation of 20 dB is required within the 500-550 MHz spectrum. The low insertion loss of 0.4 dB makes it suitable for applications where signal integrity is critical. Consider the SMA-FEMALE interface for standard coaxial connections and verify that the 300 W power rating meets the system's peak and average power demands.

RF Circulators And Isolators Part Context

This component belongs to the D3I0555 series of RF isolators from DiTom Microwave. It shares the same frequency range and physical dimensions as other variants in the family but differs in isolation performance, such as the 40 dB variant (D4I0555). The D3I0555-1 specifically denotes the 20 dB isolation model within this product line.

RF Circulators And Isolators Replacement Considerations

The D4I0555-1 offers higher isolation at 40 dB with increased insertion loss of 0.8 dB. The D3C0555-3 is a circulator rather than an isolator and uses different port configurations. Verify functional equivalence before substitution.
