D3C4012-1

RF Circulators And Isolators Overview

The D3C4012-1 is a single junction coaxial circulator manufactured by DiTom Microwave, operating within a frequency range of 4.00 GHz to 12.00 GHz. It features SMA connectors with a male port and two female ports. The device supports an average forward power rating of 20 W. Key electrical specifications include an insertion loss of 1 dB, an isolation of 14 dB, and a voltage standing wave ratio (VSWR) of 1.5:1. The unit is housed in a module package measuring 1 inch by 0.5 inch by 1 inch, constructed from passivated stainless steel with gold-plated contacts.

RF Circulators And Isolators Feature Summary

• Single junction coaxial design for directional signal routing
• Magnetic shielding integrated within the stainless steel housing
• Gold-plated SMA interface connections ensuring reliable RF contact

RF Circulators And Isolators Applications

• Transmitter-receiver switching in radar systems
• Duplexing in communication transceivers
• Signal separation in microwave measurement setups

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration required for your circuit, as this model utilizes a male port alongside two female ports. Confirm that the 20 W average power rating aligns with your system's thermal management capabilities. Ensure the operating temperature range of +10°C to +60°C meets your environmental requirements before finalizing the order.

RF Circulators And Isolators Selection Notes

Select this component when a wide bandwidth covering 4 GHz to 12 GHz is necessary for a single device. The 14 dB isolation provides adequate signal separation for many standard applications. Consider the physical dimensions of 1x0.5x1 inch for board space planning. The solder tab installation style requires appropriate mounting infrastructure on the PCB or chassis.

RF Circulators And Isolators Part Context

This part belongs to the D3C4012 series of RF circulators from DiTom Microwave. The series includes variants such as the D3C4012YMG-1, which offers cryogenic performance and magnetic shielding, and the standard D3C4012. The D3C4012-1 specifically denotes the version with solder tab mounting and standard SMA interfaces, distinguishing it from other packaging options in the family.

RF Circulators And Isolators Replacement Considerations

The D3C4012 serves as a direct functional equivalent within the same product line. For applications requiring cryogenic operation, the D3C4012YMG-1 is the designated alternative. Verify that any substitute maintains the 4-12 GHz frequency range and compatible SMA connector types.
