D3C1722S

RF Circulators And Isolators Overview

The D3C1722S is a three-port RF circulator manufactured by DiTom Microwave, designed for operation within the 1.7 GHz to 2.2 GHz frequency range. It features SMA female connectors on all ports and utilizes a passivated stainless steel housing with gold-plated contacts. The component supports an average forward power rating of 150 W, ensuring robust performance in high-power applications. Key electrical specifications include a maximum insertion loss of 0.4 dB, providing efficient signal transmission. The device maintains a voltage standing wave ratio (VSWR) of 1.25:1, indicating excellent impedance matching across the operational band. Additionally, it offers an isolation level of 20 dB between non-adjacent ports, which is critical for minimizing signal interference in complex RF systems.

RF Circulators And Isolators Feature Summary

• Provides directional signal flow control through a three-port architecture
• Constructed with passivated stainless steel for environmental durability
• Features gold-plated SMA female connectors for reliable interfacing

RF Circulators And Isolators Applications

• L-band and S-band RF wireless communication systems
• Transmitter and receiver signal separation in radar setups
• Antenna switching networks requiring low insertion loss

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration and mounting style against project requirements before ordering. Confirm that the operating temperature range of -20°C to +65°C aligns with the intended environment. Ensure that the 150 W power handling capacity meets system peak load demands. Check RoHS3 compliance status if required by regulatory standards. Validate that the module dimensions fit within the designated enclosure space.

RF Circulators And Isolators Selection Notes

Select this model when a dedicated circulator is needed for the 1.7–2.2 GHz band with moderate power handling. Consider the physical size and solder tab installation method during PCB layout planning. Evaluate whether the 20 dB isolation level suffices for the specific application's noise floor requirements. Compare insertion loss specifications against alternative components to ensure optimal system efficiency. Verify compatibility with existing SMA-based interconnect infrastructure.

RF Circulators And Isolators Part Context

This component belongs to the D3C1722 series of RF circulators from DiTom Microwave. Variants such as D3C1722S-3 and D3C1722S-7 share similar core electrical characteristics but may differ in packaging or connector configurations. The D3C1722S represents a standard module form factor suitable for general-purpose RF applications. It is distinct from isolators by its multi-port circulation functionality rather than single-direction absorption.

RF Circulators And Isolators Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Cross-reference part numbers like D3C1722S-3 or D3C1722S-7 only if their specific connector formats match the design needs. Ensure any replacement maintains the same frequency range and power ratings.
