R570F53100

Overview

The Radiall R570F53100 is a coaxial switch belonging to the Ramses series, designed for high-frequency applications up to 26.5 GHz. It features an SMA connector interface with a 50 Ohm impedance and SPDT contact configuration. The device utilizes a latching mechanism with self-cut-off functionality, powered by 28Vdc TTL control signals. Key electrical specifications include a VSWR of 1.25:1, insertion loss of 0.25 dB, and isolation of 75 dB. It operates within a temperature range of -40°C to +85°C and offers a mechanical life of 2,500,000 cycles.

Feature Summary

• High-frequency operation capability up to 26.5 GHz
• Latching mechanism with self-cut-off power management
• SPDT contact configuration for signal routing
• SMA connector interface for standard integration

Applications

• Test and measurement equipment requiring precise RF signal switching
• Telecommunications infrastructure systems
• Aerospace and defense radar systems

Procurement Notes

Verify the specific datasheet version for the R570F53100 to confirm exact pinout and control voltage tolerances. Ensure compatibility with the 28Vdc TTL drive requirements in the host system design. Check for RoHS compliance status if environmental regulations apply to the final assembly. Confirm availability through authorized Radiall distributors as supply chain conditions may vary.

Selection Notes

Select this component when a latching RF switch is required to maintain state without continuous power consumption. The 26.5 GHz frequency rating makes it suitable for microwave applications beyond standard X-band limits. Compare the 0.25 dB insertion loss against system budget constraints. Consider the SMA interface compatibility with existing cabling and fixture designs before finalizing the selection.

Part Context

This part belongs to the Ramses family of coaxial switches from Radiall, known for robust performance in demanding environments. The R570 series typically encompasses various connector types and frequencies, with the F suffix often indicating SMA interfaces. This specific model integrates solid-state or electromechanical reliability features tailored for critical signal path management in professional RF systems.

Replacement Considerations

Direct substitutes within the Ramses series may include other SPDT variants with similar frequency ratings but different connector types or control voltages. Verify that any alternative maintains the 26.5 GHz operational limit and 50 Ohm impedance. Cross-reference pin assignments and latching mechanisms to ensure functional equivalence without redesigning the control circuitry.
