The **KWVS2-2CC-R** is a specific part number belonging to the **KWVS2 Series** of Coaxial Switches (specifically SPDT Transfer Switches) manufactured by **Mini-Circuits**. These components are critical in RF (Radio Frequency) and Microwave engineering for routing signals between different paths with high precision and low loss. --- ### 1. Technical Specifications The "2CC" designation typically refers to the control voltage and connector configuration. Below is a breakdown of the typical electronic characteristics for this series: | Parameter | Specification | | :--- | :--- | | **Switch Type** | SPDT (Single Pole Double Throw) | | **Frequency Range** | DC to 18 GHz (varies by sub-model) | | **Impedance** | 50 $\Omega$ | | **Control Voltage** | +24V to +28V DC (Typical for CC models) | | **Insertion Loss** | 0.20 dB to 0.50 dB (Frequency dependent) | | **Isolation** | 60 dB to 90 dB | | **Switching Time** | 20 ms (Maximum) | | **Connector Type** | SMA Female | --- ### 2. Part Number Breakdown Understanding the nomenclature helps identify the specific electronic behavior of the unit: * **KWVS**: Series designation for Mini-Circuits Coaxial Switches. * **2**: Indicates the specific mechanical/electrical design iteration. * **2CC**: * The first **2** usually refers to the voltage requirement (e.g., 24V). * **CC** indicates the control circuit type, often representing "Failsafe" or "Latching" with specific pin configurations. * **R**: Typically stands for **RoHS Compliant**, meaning the part is manufactured without hazardous substances like lead. --- ### 3. Key Electronic Components & Internal Design The device is an electromechanical switch. Internally, it consists of: 1. **Solenoid Actuator:** An electromagnetic coil that moves the internal contacts when DC voltage is applied. 2. **RF Contacts:** Precision-machined gold-plated contacts designed to maintain a 50-ohm environment to prevent signal reflection (VSWR). 3. **Control Interface:** A multi-pin connector (or solder terminals) used to apply the switching voltage. 4. **Indicator Circuitry:** Some versions include internal sensors to provide feedback to the system, confirming the switch has physically moved to the desired position. --- ### 4. Typical Applications * **Test & Measurement:** Routing signals from a single Signal Generator to multiple Devices Under Test (DUT). * **Satellite Communications:** Switching between primary and redundant low-noise amplifiers (LNAs). * **Base Stations:** Antenna switching and signal path routing in cellular infrastructure. --- ### 5. Control Truth Table (General) For a standard SPDT configuration: | Control Voltage | Signal Path | | :--- | :--- | | 0V (De-energized) | J1 to J2 (Common to Normally Closed) | | +24V (Energized) | J1 to J3 (Common to Normally Open) |
