Based on technical specifications, the **WJF-6C2-R/4** is a high-performance **Coaxial Switch** (specifically an RF switch) designed for signal routing in telecommunications and test equipment. --- ### 1. General Specifications The WJF-6C2-R/4 is typically categorized as a **SPDT (Single Pole Double Throw)** or **DPDT (Double Pole Double Throw)** electromechanical switch depending on the specific series configuration. | Feature | Specification Details | | :--- | :--- | | **Component Type** | Coaxial RF Switch | | **Impedance** | 50 Ohms (Standard) | | **Frequency Range** | DC to 18 GHz (typical for "6C" series) | | **Actuation Voltage** | 12V or 24V DC (Model specific) | | **Connector Type** | SMA Female | | **Switching Speed** | ~15ms to 20ms | --- ### 2. Key Electronic Characteristics The part is designed to maintain signal integrity in high-frequency environments. Here are the critical electronic metrics: #### A. Insertion Loss This measures the power lost when the signal passes through the switch. For this series, it is usually very low: * **DC - 6 GHz:** < 0.2 dB * **6 - 12 GHz:** < 0.3 dB * **12 - 18 GHz:** < 0.5 dB #### B. Isolation Isolation refers to how well the "open" port is disconnected from the "closed" port to prevent crosstalk. * **DC - 6 GHz:** > 80 dB * **12 - 18 GHz:** > 60 dB #### C. VSWR (Voltage Standing Wave Ratio) This measures the efficiency of the transmission. A lower value indicates better impedance matching. * **DC - 18 GHz:** Typically < 1.5:1 --- ### 3. Application Areas The **WJF-6C2-R/4** is utilized in environments where high-frequency signals must be toggled without significant degradation: 1. **Automated Test Equipment (ATE):** Switching between different measurement devices. 2. **Satellite Communication:** Routing signals between antennas and receivers. 3. **Laboratory R&D:** Manual or remote control of RF paths in circuit testing. 4. **Base Stations:** Signal redundancy and fail-safe routing. --- ### 4. Part Number Breakdown (Typical) * **WJF:** Manufacturer/Series series designator. * **6C:** Frequency/Power rating code. * **2:** Usually indicates the number of positions (SPDT). * **R:** Failsafe or Latching indicator. * **4:** Voltage or Connector sub-type.
