The **CCP-47NXE-RMS** is a specialized high-performance coaxial switch manufactured by **Teledyne Relays**. It is part of the CCP-47 series, designed for applications requiring high reliability and signal integrity in RF (Radio Frequency) circuits. --- ### 1. Technical Specifications The following table outlines the primary electronic and physical characteristics of the CCP-47NXE-RMS: | Feature | Specification | | :--- | :--- | | **Switch Type** | SPDT (Single Pole Double Throw) | | **Frequency Range** | DC to 12.0 GHz | | **Coaxial Connector** | SMA (Female) | | **Actuator Voltage** | 24V - 28V DC | | **Actuator Type** | Failsafe | | **Impedance** | 50 Ohms | | **RF Contacts** | Break-before-make | --- ### 2. Breakdown of the Model Suffixes The alphanumeric code provides specific details about the electronic configuration: * **CCP-47**: The base series for commercial, high-frequency SPDT coaxial switches. * **N**: Indicates the **Actuator Type**. "N" typically refers to Narrowbody or specific mounting configurations. * **X**: Represents **Enclosure/Circuitry**. Usually indicates the inclusion of internal terminations or specific suppression diodes. * **E**: Refers to **Enhanced** performance or environmental sealing (often related to moisture resistance). * **RMS**: Indicates **RoHS Compliant** (R), **Manual Override** (M), or specific **Solder terminals** (S) depending on the production batch, though primarily denotes the Mounting and Terminal style. --- ### 3. Key Electronic Components & Features #### A. Failsafe Actuation Unlike a "latching" switch, the failsafe mechanism in this unit requires continuous current to stay in the energized position. If power is lost, the switch automatically returns to its "de-energized" (default) state. #### B. RF Performance Metrics To ensure signal purity, the internal components are engineered for: * **High Isolation:** Minimizing signal leakage between ports (typically >60dB at high frequencies). * **Low Insertion Loss:** Reducing power loss as the signal passes through the switch. * **Low VSWR:** Minimizing signal reflection back to the source. #### C. Control Circuitry The device includes internal suppression to protect the driving electronics from back-EMF (Electromotive Force) spikes generated by the inductive coil during switching. --- ### 4. Typical Applications * **Telecommunications:** Signal routing in base stations. * **Test & Measurement:** Automated test equipment (ATE) for RF components. * **Satellite Comm:** Ground station signal switching. * **Military/Aerospace:** High-reliability RF signal distribution.
