R570452010

Overview

The R570452010 is an SPDT coaxial switch from the RAMSES series, operating up to 18 GHz with a 50 Ohm impedance. It features SMA connectors and solder pin terminals. The device utilizes a latching mechanism with self-cut-off control at 12 VDC. Key electrical parameters include a maximum insertion loss of 0.35 dB, a minimum isolation of 60 dB, and a VSWR of 1.4:1. It supports TTL diode inputs and includes positive common configuration.

Feature Summary

• Latching operation with self-cut-off power management for energy efficiency
• High-frequency performance up to 18 GHz with low insertion loss
• Integrated status indicators and TTL diode input compatibility
• Robust mechanical design with solder pin termination

Applications

• Test and measurement instrumentation
• Telecommunications base stations
• Aerospace and defense radar systems
• Automotive radar development

Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm voltage requirements and connector type. Ensure the ordering information matches the required latching logic and terminal style. Cross-reference the part number with authorized distributors to confirm current availability and lead times. Check for any recent revisions in the product documentation that may affect compatibility.

Selection Notes

Select this component for applications requiring high-isolation switching within the microwave frequency range. The 12 VDC latching feature reduces power consumption compared to continuous coil drive options. Consider the SMA interface compatibility with existing PCB layouts. Evaluate the thermal operating range against environmental conditions. Confirm the positive common configuration meets circuit design requirements.

Part Context

This part belongs to Radiall's RAMSES family of coaxial switches, designed for high-reliability RF signal routing. The series offers various configurations including SPDT and DPDT options with different frequency ranges and control voltages. These switches are engineered for demanding environments, providing consistent performance across wide temperature ranges.

Replacement Considerations

Direct substitutes include R570452100 (12VDC, non-latching) and R570452010 variants with different control logic. Verify interface compatibility and voltage levels when swapping. Consult the manufacturer's cross-reference guide for approved alternatives.
