R570453010

Overview

The R570453010 is a general-purpose RF coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It features an SPDT configuration with SMA connectors and operates up to 18 GHz. The device utilizes a latching mechanism with self-cut-off functionality, driven by a 28 VDC positive common coil voltage. Key electrical parameters include a 50 Ohm impedance, 0.35 dB insertion loss, 60 dB isolation, and a VSWR of 1.4:1. It supports 10,000,000 cycles and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Latching operation with self-cut-off coil drive for energy efficiency
• Integrated fail-safe indicators for state verification
• High-cycle durability rated at 10 million operations
• SMA connector interface for standard RF integration

Applications

• Telecommunications base station signal routing
• Test and measurement equipment switching matrices
• Electronic warfare systems requiring reliable RF path selection
• Aerospace and defense radar subsystems

Procurement Notes

Verify component authenticity through authorized Radiall distributors or certified partners. Confirm lot traceability and RoHS/REACH compliance documentation upon receipt. Inspect SMA connectors for physical damage during handling. Ensure storage conditions remain within specified humidity limits to prevent corrosion. Validate part markings against official datasheet specifications before installation.

Selection Notes

Select this model when a latching SPDT switch with integrated status indication is required. The self-cut-off feature reduces power consumption compared to continuous energization designs. Verify that the 28 VDC control voltage aligns with system logic levels. Ensure the SMA interface matches existing board layout constraints. Consider the 18 GHz frequency limit for high-speed signal applications.

Part Context

This component belongs to the Ramses family of coaxial switches, designed for robust performance in demanding RF environments. The series offers various configurations including different pole counts and connector types. The R570453010 specifically addresses needs for reliable, low-loss switching with visual feedback capabilities in compact modules.

Replacement Considerations

Direct substitutes within the Ramses series may include variants with different termination styles or indicator options. Cross-reference specific pinouts and control voltages when considering alternative SPDT models. Ensure replacement parts maintain the same 18 GHz frequency rating and 50 Ohm impedance characteristics.
