The **CCP-33SXD-RNS** is a high-performance coaxial switch manufactured by Teledyne Relays (specifically within their Coaxial Switches division). This specific model belongs to the **CCP-33 Series**, which consists of SPDT (Single Pole Double Throw) electromechanical switches designed for microwave frequencies. --- ### 1. Technical Specifications The following table outlines the primary electronic and physical characteristics of the CCP-33SXD-RNS: | Parameter | Specification | | :--- | :--- | | **Switch Type** | SPDT (Single Pole Double Throw) | | **Actuator Type** | Failsafe | | **Frequency Range** | DC to 18 GHz | | **Impedance** | 50 Ohms | | **Operating Voltage** | 24V to 30V DC (Typical 28V) | | **RF Connector** | SMA (Female) | | **Actuation Current** | ~140 mA @ 28VDC | | **Switching Time** | 15 ms (Max) | --- ### 2. Breakdown of Model Suffixes The alphanumeric code provides specific details about the component's internal circuitry and physical interface: * **CCP-33**: The basic series (Commercial SPDT, DC-18GHz). * **S**: **SMA Connectors**. Standard interface for microwave applications. * **X**: **Failsafe**. This means the switch returns to a "default" position when power is removed. * **D**: **Indicators**. Includes internal circuitry to provide a logic signal indicating the current state of the switch. * **R**: **TTL Driver**. Allows the switch to be controlled via low-power logic signals (0-5V) rather than switching the full 28V supply. * **NS**: **Narrow Shell**. A compact housing design for high-density PCB or chassis mounting. --- ### 3. Key Features & Applications #### Electronic Features * **High Isolation**: Maintains signal integrity by preventing leakage between the "on" and "off" ports (typically >60dB at high frequencies). * **Low Insertion Loss**: Minimizes signal power loss as it passes through the switch. * **TTL Compatibility**: The "R" designation allows direct interface with microcontrollers or FPGA control logic without needing external power transistors. #### Typical Applications 1. **Automated Test Equipment (ATE)**: Routing signals between a Device Under Test (DUT) and measurement instruments. 2. **Telecommunications**: Switching between primary and redundant signal paths in base stations. 3. **Satellite Communications**: High-reliability RF signal routing. --- ### 4.
