D3C0890-5

RF Circulators And Isolators Overview

The D3C0890-5 is a three-port RF circulator manufactured by DiTom Microwave, designed for operation within the 800 MHz to 900 MHz frequency range. It features SMA female connectors and supports an average forward power rating of 250 W. Key electrical specifications include an insertion loss of 0.3 dB, an isolation level of 23 dB, and a voltage standing wave ratio (VSWR) of 1.25. The component utilizes a passivated stainless steel body with gold-plated contacts and operates within a temperature range of -20°C to +65°C.

RF Circulators And Isolators Feature Summary

• Provides non-reciprocal signal routing for three-port microwave applications
• Constructed with passivated stainless steel housing for environmental durability
• Supports high average forward power handling capabilities

RF Circulators And Isolators Applications

• RF and microwave communication systems
• Transmitter output protection circuits
• Receiver input isolation stages

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration and pinout orientation against the official datasheet before integration, as variations may exist within the product family. Confirm that the operating environment remains within the specified temperature limits and that the required power levels do not exceed the 250 W average forward power rating. Ensure compatibility with SMA female interfaces on the host circuit board or cable assembly.

RF Circulators And Isolators Selection Notes

Select this model when a circulator is required specifically for the 800 MHz to 900 MHz band with moderate power handling needs. Consider the 0.3 dB insertion loss and 23 dB isolation metrics for system efficiency requirements. Evaluate the physical dimensions and mounting style against available space constraints in the design.

RF Circulators And Isolators Part Context

This component belongs to the D3C0890 series of RF circulators from DiTom Microwave. The series offers variants tailored for the same frequency range but potentially differing in connector configurations or internal junction structures. It serves as a passive magnetic device essential for directing signal flow in unidirectional paths within microwave networks.

RF Circulators And Isolators Replacement Considerations

Direct substitutes within the same series include D3C0890-1, D3C0890-3, D3C0890-4, and D3C0890-7. Verify that alternative part numbers match the required connector types and mechanical footprint before substitution.
