## Overview of CCR-53S70-R The **CCR-53S70-R** is a high-performance **Electromechanical Coaxial Switch** manufactured by Teledyne Relays. It belongs to the CCR-53 series, which are typically SPDT (Single Pole Double Throw) switches designed for routing RF signals with minimal loss across a wide frequency range. --- ### Technical Specifications The following table outlines the primary electronic and physical characteristics of the device: | Parameter | Specification | | :--- | :--- | | **Switch Type** | SPDT (Single Pole Double Throw) | | **Frequency Range** | DC to 26.5 GHz | | **Impedance** | 50 Ohms | | **Actuator Voltage** | 28 VDC (Typical for '70' series) | | **Actuator Type** | Latching | | **Connector Type** | SMA (Female) | | **Operating Temperature** | -55°C to +85°C | --- ### Key Electronic Components & Features #### 1. Latching Actuator Unlike "Failsafe" switches that require continuous power to stay in a specific position, the **Latching** mechanism in the CCR-53S70-R only requires a pulse of current to change states. Once shifted, it remains in that position without further power consumption, reducing heat dissipation. #### 2. Internal Terminations The "70" designation often implies specific features regarding internal termination or circuit configuration. These switches are designed to provide high **Isolation** (preventing signal leakage between ports) and low **Insertion Loss** (minimizing signal strength reduction). #### 3. RF Contacts The internal contacts are engineered using specialized gold-plated materials to ensure: * Low contact resistance. * Repeatability over millions of switching cycles. * Power handling capability for RF signals. --- ### Application Use Cases 1. **Automated Test Equipment (ATE):** Routing signals from a single source to multiple testing points. 2. **Satellite Communications:** Switching between primary and redundant signal paths. 3. **Broadband Communications:** Used in infrastructure where high-frequency signal integrity is critical. ---
