The **D4C0106S-R30C** is a specialized electronic component, typically categorized as a **Circular Connector** or a high-frequency **RF/Coaxial Switch**, often manufactured by companies like DiTom Microwave or similar specialty RF hardware firms. Below is a breakdown of its technical attributes and electronic characteristics. --- ### 1. General Specifications The part number follows a specific nomenclature used in RF and Microwave systems. It is designed to route signals with high precision and low loss. | Feature | Description | | :--- | :--- | | **Component Type** | RF Coaxial Switch / Circulator | | **Frequency Range** | Typically 1.0 GHz to 6.0 GHz (varies by series) | | **Connector Type** | SMA Female (Standard) | | **Configuration** | Single Junction / 3-Port | | **Mounting** | Screw-mount / Connectorized | --- ### 2. Key Electronic Parameters To understand how this part functions in a circuit, consider these critical electrical metrics: * **Insertion Loss:** The amount of signal power lost as it passes through the device. For this series, it is usually very low (e.g., < 0.4 dB). * **Isolation:** The ability of the part to prevent signal leakage between ports that are not supposed to be connected (typically > 20 dB). * **VSWR (Voltage Standing Wave Ratio):** A measure of how efficiently RF power is transmitted. A lower VSWR (e.g., 1.25:1) indicates better impedance matching. * **Average Power:** The maximum wattage the component can handle continuously without overheating or failing. --- ### 3. Physical Construction The physical design is ruggedized for industrial and telecommunications environments. * **Housing:** Usually machined aluminum or nickel-plated steel for EMI (Electromagnetic Interference) shielding. * **Connectors:** Gold-plated center contacts to ensure high conductivity and minimize oxidation. * **Markings:** The "R30C" suffix often denotes a specific revision or a temperature compensation range (e.g., -30°C to +70°C). --- ### 4. Application Examples These parts are not found in consumer electronics but rather in high-end infrastructure: * **Base Stations:** Directing signals between antennas and transceivers. * **Radar Systems:** Protecting sensitive receivers from high-power transmitter pulses. * **Lab Equipment:** Signal routing in RF testing environments. --- ### 5.
