R574303825

Overview

The R574303825 is an SP8T coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It operates within a frequency range of 0 MHz to 3 GHz and provides 80 dB isolation. The device features a normally open configuration and utilizes a D-sub connector for control interface. Designed for terminated applications, it supports 28Vdc TTL input signals. This component is classified as obsolete in the current product lifecycle.

Feature Summary

• SP8T configuration with terminated design
• Operates up to 3 GHz frequency
• Normally open switching state
• D-sub connector control interface

Applications

• RF signal routing in communication systems
• Test and measurement equipment
• Aerospace and defense radar systems

Procurement Notes

Verify obsolescence status before procurement planning. Confirm compatibility with existing D-sub control wiring. Check for available stock through authorized distributors or secondary markets. Ensure 28Vdc TTL signal levels match system requirements. Review datasheet for mechanical dimensions and pinout definitions.

Selection Notes

Consider the SP8T topology for eight-channel signal distribution needs. Evaluate the 3 GHz bandwidth against application frequency requirements. Assess the terminated design impact on system impedance matching. Verify the D-sub connector type aligns with available cabling infrastructure.
