The **M2AS1-4144-R** is a specific electronic component belonging to the category of **High-Frequency (RF) Coaxial Switches**. Specifically, it is a high-performance electromechanical switch often used in microwave and RF signal routing. --- ### Technical Specifications Below are the primary electronic characteristics typical for this class of component: | Feature | Specification Details | | :--- | :--- | | **Component Type** | Electromechanical Coaxial Switch | | **Switch Configuration** | SPDT (Single Pole Double Throw) | | **Actuator Type** | Failsafe (usually returns to a default position when power is removed) | | **Frequency Range** | DC up to 18 GHz or 26.5 GHz (depending on sub-series) | | **Impedance** | 50 Ohms | | **Connector Type** | SMA Female | | **Voltage Supply** | Typically 12V or 28V DC | --- ### Key Internal Components The "electronic parts" within this assembly consist of several sub-systems: 1. **Solenoid/Actuator:** An electromagnetic coil that converts electrical energy into mechanical motion. When current flows through the coil, it creates a magnetic field that moves an internal plunger (armature). 2. **Contact Mechanism:** Precision gold-plated contacts designed to maintain low insertion loss and high isolation. These physical reeds move to bridge the signal path between the input and the selected output port. 3. **Diodes (Suppression):** Most modern RF switches include internal "spark-suppression" diodes across the coil to protect the driving circuit from back-EMF spikes when the switch is toggled. 4. **Housing/Shielding:** A rugged, milled aluminum or stainless steel housing designed to prevent electromagnetic interference (EMI) and provide environmental sealing. --- ### Functional Application The M2AS1-4144-R is primarily used in high-reliability environments where signal integrity is critical: * **Automated Test Equipment (ATE):** Routing signals from a single source to multiple units under test. * **Satellite Communications:** Switching between primary and redundant signal paths. * **Radar Systems:** Directing high-frequency pulses between transmitter and receiver modules. ---
