The **CCR-53S80-R** is a high-performance, electromechanical coaxial switch manufactured by **Teledyne Relays**. It is specifically designed for high-frequency RF (Radio Frequency) applications where signal integrity and reliability are paramount. --- ## 1. Core Technical Specifications The following table summarizes the primary electrical and mechanical characteristics of the CCR-53S80-R: | Feature | Specification | | :--- | :--- | | **Switch Type** | SPDT (Single Pole Double Throw) | | **Frequency Range** | DC to 26.5 GHz | | **Actuator Type** | Latching | | **Operating Voltage** | 28V DC | | **Impedance** | 50 Ohms | | **Connector Type** | SMA (Female) | | **Actuator Current** | ~140 mA @ 28V | | **Switching Time** | 15 ms (Maximum) | --- ## 2. Key Electronic Components & Design ### Actuation Mechanism (Latching) Unlike "failsafe" switches that require continuous power to stay in a specific position, the **Latching** mechanism in this part uses a pulse of current to switch states. Once switched, it remains in that position without needing further power. This significantly reduces power consumption and heat dissipation within the system. ### RF Path Performance The electronic design focuses on maintaining a clean RF path. At high frequencies (up to 26.5 GHz), the part is engineered for: * **Low Insertion Loss:** Minimizes signal strength reduction as it passes through the switch. * **High Isolation:** Prevents signal leakage between the "on" and "off" ports. * **Low VSWR (Voltage Standing Wave Ratio):** Ensures minimal signal reflection, protecting sensitive transmitters. ### Integrated Features (S-Suffix and R-Suffix) * **S-Suffix:** Typically indicates the inclusion of a D-sub connector or specific terminal configuration for control. * **R-Suffix:** Refers to the "RoHS" compliance, meaning the part is manufactured without hazardous substances like lead. * **Internal Circuitry:** Includes suppression diodes to protect the control circuit from "back EMF" (voltage spikes) generated by the internal relay coils when the power is removed. --- ## 3. Applications The CCR-53S80-R is commonly found in the following electronic environments: 1. **Automated Test Equipment (ATE):** Routing high-frequency signals between instruments and devices under test. 2. **Satellite Communications:** Switching between primary and redundant signal paths. 3. **Military Radar:** High-reliability switching in harsh RF environments. ---
