The **M2AMS2-162-R2/N** is a specialized microwave/RF coaxial switch, typically manufactured by companies like **Teledyne Relays** or similar high-reliability aerospace component providers. This part belongs to the **M2A** series, which are characterized by their miniature size and high-frequency performance. --- ### 1. Component Overview This device is a **SPDT (Single Pole Double Throw)** electromechanical coaxial switch. It is designed to route RF signals from one common input to one of two output ports. | Feature | Specification Details | | :--- | :--- | | **Switch Type** | SPDT (Single Pole Double Throw) | | **Actuator Type** | Failsafe (usually returns to a default position when power is removed) | | **Frequency Range** | DC to 18 GHz (or 26.5 GHz depending on specific sub-series) | | **Interface** | SMA Female Connectors | | **Series** | M2A (Miniature Coaxial Switch) | --- ### 2. Breakdown of the Model Number The alphanumeric code provides specific details regarding the electrical and mechanical configuration: | Segment | Meaning | | :--- | :--- | | **M2A** | Series designation: Miniature Electromechanical Coaxial Switch. | | **MS2** | Configuration: Indicates a **SPDT** switch with a specific mounting or housing style. | | **162** | Electrical Specs: Often denotes the **Coil Voltage** (e.g., 12V or 28V) and current consumption. | | **R2** | Actuation: Typically refers to **Failsafe** operation with specific connector orientations. | | **N** | Options: Often indicates "No TTL" (Direct coil control) or specific plating/environmental sealing. | --- ### 3. Key Electronic Characteristics The "electronic" side of this part involves the **DC Coil** that moves the internal mechanical linkage to bridge the RF path. * **Coil Voltage:** Usually operates on **28VDC** (standard for aviation/defense), though 12V variants exist. * **Switching Time:** Extremely fast for a mechanical part, typically under **15ms**. * **RF Performance:** * **Insertion Loss:** Very low (typically <0.5 dB). * **Isolation:** High (typically >60 dB), preventing signal leakage between ports. * **VSWR:** Low (usually <1.5:1), ensuring minimal signal reflection. --- ### 4. Common Applications Due to its high reliability and precision, this part is used in: * **Aerospace & Defense:** Signal routing in radar and communication arrays. * **Test & Measurement:** Automated test equipment (ATE) for switching between different RF signal sources. * **Satellite Communications:** Switching between primary and redundant signal paths. --- ### 5.
