D3I0102N-3

RF Circulators And Isolators Overview

The D3I0102N-3 is a single junction RF isolator manufactured by DiTom Microwave, designed for operation within the 1 GHz to 2 GHz frequency range. It features Type-N female connectors and supports an average forward power rating of 50 W. Key electrical specifications include an isolation of 18 dB, insertion loss of 0.5 dB, and a VSWR of 1.3. The module housing measures 2.8 inches by 1 inch by 2.8 inches, constructed from nickel-plated brass with gold-plated copper contacts. It operates between +10°C and +55°C.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission to protect source components from reflected power in RF systems.
• Utilizes a single junction ferrite design to achieve high isolation performance across the specified bandwidth.
• Features robust metallic construction with gold-plated contacts for reliable signal integrity and corrosion resistance.

RF Circulators And Isolators Applications

• Protecting microwave transmitters and amplifiers from load mismatches.
• Isolating stages in radar and communication system signal chains.
• Testing setups requiring stable source impedance under varying load conditions.

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration and datasheet revision when sourcing, as distributor listings may reference similar part numbers like D3I0102N without suffixes. Confirm RoHS3 compliance status directly with the manufacturer or authorized supplier documentation prior to order placement. Ensure the receiving facility can accommodate the module's physical dimensions and thermal requirements during installation.

RF Circulators And Isolators Selection Notes

Select this component when a 50 W power handling capability is required within the 1-2 GHz band. The Type-N interface suits applications needing standard coaxial connections. Consider the 18 dB isolation level against system noise floor requirements. Verify that the operating temperature range aligns with the environmental conditions of the intended deployment site.

RF Circulators And Isolators Part Context

This model belongs to DiTom Microwave's single junction isolator series, which offers various connector options including SMA and 2.92mm. The D3I0102N-3 specifically denotes the Type-N female variant. It shares core electrical characteristics with other models in the D3I0102 family but differs in interface geometry and mechanical mounting specifications.

RF Circulators And Isolators Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate generic 1-2 GHz Type-N isolators with matching 50 W power ratings and comparable VSWR metrics if exact replacement is unavailable.
