D4I1722S-1

RF Circulators And Isolators Overview

The DiTom Microwave D4I1722S-1 is a coaxial isolator designed for the 1.7 GHz to 2.0 GHz frequency range. It features SMA female connectors and operates within a module package configuration. The component supports an average forward power of 150 W, providing 40 dB of isolation. Key electrical specifications include a maximum insertion loss of 0.8 dB and a Voltage Standing Wave Ratio (VSWR) of 1.25.

RF Circulators And Isolators Feature Summary

• Provides high isolation performance of 40 dB to protect sensitive RF components from reflected signals.
• Features low insertion loss of 0.8 dB to minimize signal attenuation in the transmission path.
• Supports high average forward power handling up to 150 W for robust operation.
• Utilizes SMA female connectors for standard coaxial interface compatibility.

RF Circulators And Isolators Applications

• RF signal transmission systems requiring unidirectional wave propagation
• Protection of microwave sources such as amplifiers and oscillators
• Test and measurement instrumentation setups

RF Circulators And Isolators Procurement Notes

Verify the specific suffix -1 against official DiTom Microwave documentation to confirm connector type and electrical tolerances. Ensure the required frequency range aligns with the 1.7 GHz to 2.0 GHz specification. Confirm RoHS3 compliance status if environmental regulations apply to the assembly. Cross-reference the part number with authorized distributors to ensure authenticity and availability.

RF Circulators And Isolators Selection Notes

Select this model when a 1.7 to 2.0 GHz operating band is required with high isolation capabilities. The 150 W power rating suits applications demanding significant power handling without thermal degradation. The SMA interface ensures compatibility with standard coaxial cabling. Consider the 0.8 dB insertion loss impact on system gain budgets during design integration.

RF Circulators And Isolators Part Context

This component belongs to the DiTom Microwave series of single-junction coaxial isolators. These devices are engineered to allow signal flow in one direction while absorbing reflections in the reverse direction. The series typically offers standardized connector options and modular packaging for easy integration into RF circuits.

RF Circulators And Isolators Replacement Considerations

The D3I1722S is a related variant offering a wider 1.7 to 2.2 GHz range but lower 20 dB isolation. Verify if the extended bandwidth or reduced isolation meets application requirements before substitution. Connector types must match exactly to avoid mechanical incompatibility.
