The **M2RT-6G-R/K** is a specialized high-frequency microwave component, typically classified as a **High Power Terminated SPDT (Single Pole Double Throw) Electromechanical Coaxial Switch**. These components are critical in RF (Radio Frequency) systems for routing signals between a common port and two output paths. ### Technical Specifications Below are the primary electronic and physical characteristics of the M2RT-6G-R/K: | Feature | Specification | | :--- | :--- | | **Frequency Range** | DC to 6 GHz | | **Switch Type** | SPDT (Single Pole Double Throw) | | **Actuator Type** | Failsafe or Latching (Model dependent) | | **Impedance** | 50 Ohms | | **RF Connectors** | SMA Female | | **Operating Voltage** | Typically 12V or 28V DC | | **Termination** | Internal 50 Ohm termination on unused ports | --- ### Core Electronic Components & Functionality #### 1. The Actuator Mechanism The "Heart" of the switch is an electromagnetic solenoid. When voltage is applied to the control pins, the magnetic field moves an internal linkage that physically shifts the RF contact. * **Terminated Logic:** In the "R/K" series, when a port is not connected to the common path, it is automatically connected to an internal 50-ohm load. This prevents signal reflections that could damage sensitive amplifiers. #### 2. RF Contact Assembly Because it operates up to 6 GHz, the internal contacts are usually gold-plated to minimize **Insertion Loss** (signal power lost during transit) and maximize **Isolation** (preventing signal leakage between ports). #### 3. Protection Circuitry * **Suppression Diodes:** Most units include diodes across the actuator coil to suppress "back EMF" (voltage spikes) that occur when the switch is toggled, protecting the external controller. * **Indicators (Optional):** Some versions include auxiliary electronic contacts that provide a feedback signal to a computer or PLC to confirm the switch has successfully moved. ### Performance Metrics * **Insertion Loss:** Generally < 0.3 dB at 6 GHz, ensuring minimal signal degradation. * **VSWR (Voltage Standing Wave Ratio):** Usually < 1.3:1, indicating excellent impedance matching. * **Switching Speed:** Typically between 15ms to 20ms. --- ### Common Applications 1. **Automated Test Equipment (ATE):** Routing a single signal generator to multiple Devices Under Test (DUT). 2. **Telecommunications:** Switching between a primary and a backup antenna. 3. **Signal Routing:** Diverting high-power RF signals into a dummy load for calibration or safety.
