D4C4012Y-2

RF Circulators And Isolators Overview

The DiTom Microwave D4C4012Y-2 is a cryogenic RF circulator designed for operation within the 4.00 to 12.00 GHz frequency range. This four-port device utilizes a dual junction configuration and features SMA connectors with mixed female and male interfaces. It is constructed from passivated stainless steel with gold-plated contacts, measuring 2 inches by 0.5 inches by 1 inch. The component supports solder tab installation and is rated for 20 W average forward power with 1 dB insertion loss and 12 dB isolation.

RF Circulators And Isolators Feature Summary

• Dual junction ferrite design for cryogenic environments
• SMA connector interface with mixed gender ports
• Passivated stainless steel housing with gold contacts

RF Circulators And Isolators Applications

• Cryogenic signal routing in radar systems
• Low-noise amplifier protection in satellite communications
• High-power microwave test and measurement setups

RF Circulators And Isolators Procurement Notes

Verify component authenticity through authorized DiTom channels due to discontinued status. Confirm specific connector gender configuration matches system requirements. Request updated datasheets for thermal performance data under vacuum conditions. Validate RoHS compliance documentation prior to integration into sensitive aerospace or defense hardware.

RF Circulators And Isolators Selection Notes

Evaluate thermal management capabilities for sub-ambient operating temperatures. Ensure mechanical dimensions fit within constrained cryostat assemblies. Compare isolation specifications against system noise floor requirements. Verify power handling limits align with peak transmit signals to prevent ferrite saturation during high-duty cycle operations.

RF Circulators And Isolators Part Context

This model belongs to the D4C4012 series of cryogenic circulators manufactured by DiTom Microwave. These components are engineered for extreme temperature stability and high linearity. The series targets applications requiring reliable non-reciprocal signal transmission where standard room-temperature devices fail due to thermal drift or magnetic instability.
