D3C0890-1

RF Circulators And Isolators Overview

The DiTom Microwave D3C0890-1 is a three-port RF circulator designed for the 800 MHz to 900 MHz frequency range. It features SMA-FEMALE connectors and supports an average forward power of 250 W. Key electrical specifications include an insertion loss of 0.3 dB, isolation of 23 dB, and a VSWR of 1.25. The device utilizes a single junction configuration with gold-plated contacts and a passivated stainless steel body. Operating temperatures range from -20°C to +65°C, and it complies with RoHS3 standards.

RF Circulators And Isolators Feature Summary

• Provides non-reciprocal signal routing within the 800 MHz to 900 MHz band using a single junction ferrite design.
• Ensures high signal integrity with low insertion loss and stable impedance matching via SMA-FEMALE interfaces.
• Constructs a durable passive component housing using passivated stainless steel with gold-plated contacts.

RF Circulators And Isolators Applications

• RF signal routing in communication systems operating at 800-900 MHz
• Transmitter-receiver isolation in radar or telemetry setups
• Integration into modular RF circuits requiring directional power flow

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration format against project requirements, as suffixes may denote port arrangements. Confirm compliance with environmental regulations such as RoHS3 and REACH status before integration. Ensure thermal management aligns with the specified operating temperature range of -20°C to +65°C. Cross-reference datasheet parameters like isolation and VSWR to validate performance suitability for the intended application bandwidth.

RF Circulators And Isolators Selection Notes

Select this model when a 250 W average power rating and 23 dB isolation are required for UHF band applications. The SMA-FEMALE interface facilitates direct connection to standard coaxial cables without adapters. Consider the physical dimensions of 1.25 x 0.73 x 1.25 inches for board layout constraints. Evaluate the single junction type for cost-effective solutions where extreme linearity is not the primary driver compared to higher-end variants.

RF Circulators And Isolators Part Context

The D3C0890-1 belongs to the D3C0890 series of coaxial ferrite circulators manufactured by DiTom Microwave. This series targets the 800-900 MHz spectrum, offering variations primarily distinguished by connector configurations and isolation levels. It represents a standard passive component solution for industrial and commercial RF infrastructure, emphasizing reliability through AS9100 Rev C compliant manufacturing processes.

RF Circulators And Isolators Replacement Considerations

The D3C0890-3 and D3C0890-5 are alternative part numbers within the same series. These substitutes share identical frequency ranges (800-900 MHz) and power ratings (250 W). Differences typically lie in the specific connector pinout or isolation characteristics. Verify mechanical footprint compatibility before substitution.

RF Circulators And Isolators FAQ

What is the isolation specification for the D3C0890-1?

The D3C0890-1 provides an isolation level of 23 dB between ports.
