D3C0780S-1

RF Circulators And Isolators Overview

The D3C0780S-1 is a three-port RF circulator manufactured by DiTom Microwave, designed for operation within the 698 MHz to 800 MHz frequency range. It features SMA female connectors on all ports and supports an average forward power of 300 W. Key electrical specifications include an insertion loss of 0.4 dB, an isolation rating of 20 dB, and a voltage standing wave ratio (VSWR) of 1.25. The component operates reliably between -20°C and +65°C.

RF Circulators And Isolators Feature Summary

• Provides non-reciprocal signal routing across three ports using a single junction design.
• Maintains low signal attenuation with specified insertion loss characteristics.
• Ensures directional signal flow through defined isolation performance metrics.

RF Circulators And Isolators Applications

• RF communication systems requiring signal direction control
• Transmitter-receiver separation in dual-channel setups
• Antenna switching applications

RF Circulators And Isolators Procurement Notes

Verify the specific suffix designation when ordering, as connector configurations may vary across the product series. Confirm that the required SMA female interface matches the system requirements. Ensure environmental ratings align with the intended operating temperature range. Check current availability status directly with authorized distributors, as stock levels fluctuate.

RF Circulators And Isolators Selection Notes

Select this model based on the strict 698 MHz to 800 MHz operational bandwidth requirement. Evaluate the 300 W power handling capacity against peak system loads. Compare the 0.4 dB insertion loss and 20 dB isolation values against system sensitivity needs. Verify physical compatibility with existing SMA female connector interfaces.

RF Circulators And Isolators Part Context

This component belongs to the D3C0780 series of RF circulators from DiTom Microwave. Variants within this family share identical core electrical parameters but differ primarily in connector types or mechanical packaging suffixes. The D3C0780S-1 specifically utilizes SMA female connectors for its three-port configuration.

RF Circulators And Isolators Replacement Considerations

Direct substitutes within the same manufacturer line include models such as D3C0780S, D3C0780S-4, D3C0780S-6, and D3C0780S-7. These alternatives maintain consistent electrical performance but may feature different connector styles or packaging options. Cross-reference connector types before substitution.
