The **CCP-37SX0-RMS** belongs to the family of coaxial switches, specifically a **failsafe SPDT (Single Pole Double Throw)** electromechanical switch designed for high-frequency RF applications. It is manufactured by Teledyne Coax Switches. --- ### 1. General Specifications This component is engineered for precision signal routing in telecommunications and test equipment. | Parameter | Specification | | :--- | :--- | | **Switch Type** | SPDT (Single Pole Double Throw) | | **Actuator Type** | Failsafe | | **Connector Type** | SMA (Female) | | **Frequency Range** | DC to 18 GHz | | **Voltage Rating** | 28V DC (Standard) | | **Impedance** | 50 Ohms | --- ### 2. Key Electronic Features #### A. Failsafe Actuation In a "Failsafe" configuration, the switch is normally closed in one position. When the control voltage (28V) is applied, the switch moves to the second position. If power is lost, the switch **automatically returns** to its default position via internal springs. #### B. RF Performance (DC - 18 GHz) As a high-frequency component, its electronic design focuses on minimizing signal degradation: * **Insertion Loss:** Very low loss (typically < 0.5dB at 18GHz) to preserve signal strength. * **Isolation:** High isolation (typically > 60dB) to prevent crosstalk between channels. * **VSWR:** Low Voltage Standing Wave Ratio to ensure impedance matching and prevent reflections. #### C. Connector Interface The **SMA connectors** are the industry standard for microwave frequencies. The "RMS" suffix often denotes specific mounting or environmental sealing features, depending on the exact sub-series. --- ### 3. Internal Components and Construction * **Solenoid Coil:** The electromagnet that moves the RF contact when energized. * **Contact Mechanism:** High-precision gold-plated contacts designed for millions of cycles. * **Housing:** Robust, EMI-shielded metal enclosure to prevent external interference. --- ### 4. Applications * **Satellite Communications:** Switching between primary and redundant signal paths. * **Automated Test Equipment (ATE):** Routing high-frequency signals from a Device Under Test (DUT) to various measurement instruments. * **Radar Systems:** High-speed signal path selection. ---
