R570563005

Overview

The R570563005 is a SPDT coaxial switch from the Ramses series, rated for frequencies up to 3 GHz. It features a latching mechanism with self-cut-off functionality and includes status indicators. The device utilizes a D-sub connector interface and operates on a 28 Vdc coil voltage. Key electrical specifications include a maximum insertion loss of 0.25 dB, an isolation of 75 dB, and a VSWR of 1.25:1. It maintains a 50 Ohm impedance and supports a mechanical life of 2,500,000 cycles within an operating temperature range of -40°C to +85°C.

Feature Summary

• SPDT configuration with latching self-cut-off operation
• Integrated status indicators for position verification
• D-sub connector interface for control signals
• High isolation and low insertion loss performance

Applications

• RF signal routing in test and measurement equipment
• Telecommunications base station switching
• Aerospace and defense radar systems
• Automated test system configurations

Procurement Notes

Verify the specific connector type and pinout configuration against your system requirements before ordering. Confirm that the 28 Vdc control voltage aligns with your power supply capabilities. Check for RoHS compliance status if environmental regulations apply to your deployment. Ensure the D-sub connector mating compatibility with existing cabling infrastructure. Validate thermal management needs for the specified operating temperature range.

Selection Notes

Select this component when a reliable SPDT switching solution is required at frequencies up to 3 GHz. The latching feature reduces power consumption by maintaining state without continuous energization. Consider the self-cut-off mechanism for enhanced safety and reliability in critical applications. The integrated indicators simplify system diagnostics and status monitoring. Evaluate the mechanical life cycle against expected switching frequency requirements.
