R573442400

Overview

The R573442400 is a single-pole four-throw (SP4T) coaxial RF switch from the Ramses series by Radiall USA, Inc. It operates within a frequency range of DC to 18 GHz and features SMA connectors. The device utilizes a latching mechanism with self-cut-off diodes for power efficiency. It requires a 12 Vdc supply voltage and accepts TTL logic inputs. The unit is housed in a module package with pins and terminals, designed for high-isolation applications up to 60 dB minimum.

Feature Summary

• Latching operation with self-cut-off diodes for reduced power consumption
• High-frequency performance extending to 18 GHz
• Integrated TTL logic interface for control simplicity
• SMA connector interface for standard coaxial integration

Applications

• Test and measurement equipment requiring signal routing
• Telecommunications infrastructure switching
• Aerospace and defense radar systems
• Electronic warfare signal processing

Procurement Notes

Verify the specific datasheet revision and pin configuration before integration, as Ramses series variants may differ in terminal layout. Confirm that the 12 Vdc TTL input levels match your system logic. Ensure the SMA connector type aligns with your PCB or cable assembly requirements. Check for any environmental compliance certifications required for your specific deployment region.

Selection Notes

Select this component when a high-frequency SP4T switch with low power consumption during steady state is required. The latching feature eliminates the need for continuous power to maintain position. Compare isolation specifications against other Ramses models if higher attenuation is needed. Ensure the operating temperature range meets your environmental constraints.

Part Context

This part belongs to the Ramses family of coaxial switches, known for robust performance in demanding RF environments. The series offers various throw configurations and connector options. The R573442400 specifically addresses needs for multi-path signal routing at microwave frequencies with efficient power management through its latching design.

Replacement Considerations

Consult official Radiall documentation for direct substitutes. Other Ramses models like R573442420 offer similar functionality but may differ in voltage or termination details. Verify compatibility with existing control circuitry before swapping.
