The **M2AS1-A134-R/N** is a specialized high-performance RF (Radio Frequency) switch component, typically used in telecommunications infrastructure, radar systems, and microwave test equipment. Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ### 1. General Overview This part belongs to a family of **Coaxial Electromechanical Switches**. Specifically, it is an SPDT (Single Pole Double Throw) switch designed to route RF signals from one common port to one of two output ports. ### 2. Technical Specifications The following table outlines the typical electrical and mechanical parameters for this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Switch Type** | SPDT (Single Pole Double Throw) | | **Actuator Type** | Failsafe or Latching (Model dependent) | | **Frequency Range** | DC to 18 GHz (or higher depending on variant) | | **Impedance** | 50 Ohms | | **Voltage** | 12V or 28V DC (indicated by the "A134" suffix) | | **Connector Type** | SMA Female | | **Operating Temp** | -25°C to +65°C | --- ### 3. Key Electronic Features * **Low Insertion Loss:** Designed to ensure minimal signal degradation as the RF wave passes through the switch. * **High Isolation:** Prevents signal leakage into the "off" port, which is critical for maintaining signal integrity in sensitive communication paths. * **Failsafe Operation:** In many "R/N" configurations, the switch returns to a default position if DC power is lost, ensuring system safety. * **High Power Handling:** Capable of handling significant CW (Continuous Wave) power compared to solid-state (semiconductor) switches. ### 4. Part Number Breakdown (Generic Structure) While manufacturer codes vary slightly (often associated with brands like Dow-Key or Teledyne), the nomenclature generally follows this logic: 1. **M2:** Often denotes the physical housing size or series generation. 2. **AS:** Indicates the switching logic (e.g., Actuator/Switching). 3. **1:** Number of poles. 4. **A134:** Specific coil voltage and internal wiring configuration (often 24-28VDC). 5. **R/N:** Usually refers to **RoHS Compliant** (R) and the specific connector orientation or indicator circuitry (N). --- ### 5. Common Applications * **Satellite Communications:** Routing signals between redundant amplifiers. * **Automated Test Equipment (ATE):** Switching between multiple Units Under Test (UUT). * **Broadcasting:** Transmitting signal path selection.
