The **WMS2-23-R/K** is a specialized high-performance electromechanical component, typically identified as a **high-frequency coaxial switch** or a **microwave relay**. These parts are designed to route Radio Frequency (RF) signals with minimal loss and high isolation. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series, here are the primary electronic characteristics: | Parameter | Typical Value / Description | | :--- | :--- | | **Frequency Range** | DC to 26.5 GHz (or 40 GHz depending on specific sub-series) | | **Actuator Type** | Latching or Failsafe (R/K denotes specific voltage/polarity) | | **Impedance** | 50 Ohms (Standard RF) | | **Connector Type** | SMA Female (Most common for this form factor) | | **Switching Speed** | ~15ms to 20ms | | **Life Cycle** | >1,000,000 cycles | --- ### 2. Breakdown of the Model Code While specific manufacturers (such as Radiall, Dow-Key, or Teledyne) use slight variations, the nomenclature generally breaks down as follows: * **WMS2**: Indicates a **Transfer Switch** (Double Pole Double Throw - DPDT). This configuration allows for swapping two signal paths simultaneously. * **23**: Usually refers to the operating voltage (e.g., 24V-28V DC) and the frequency ceiling. * **R**: Represents a **Self-Cutoff** or **Indicator** circuit feature. This protects the internal coils from overheating by cutting power once the switch has toggled. * **K**: Often denotes the connector orientation or a specific mounting bracket style (e.g., solder pins vs. D-sub connector). --- ### 3. Electronic Components Internal to the Switch Inside the WMS2-23-R/K, you will find the following electronic sub-parts: 1. **Solenoid Coils:** Electromagnetic coils that create the physical movement required to flip the RF contacts. 2. **RF Cavity:** A precision-machined gold-plated chamber that houses the reeds to ensure signal integrity. 3. **Suppression Diodes:** Most modern units include internal diodes to suppress "back EMF" (voltage spikes) that occur when the coil is de-energized, protecting the driving circuitry. 4. **Indicator Contacts:** Auxiliary circuits that allow a remote computer or controller to verify the physical position of the switch (Open/Closed). --- ### 4. Common Applications * **Satellite Communications:** Routing signals between primary and redundant amplifiers. * **Automated Test Equipment (ATE):** Switching between multiple Devices Under Test (DUT). * **Radar Systems:** Directing high-frequency pulses between transmitter and receiver modules.
