R573402000

Overview

The Radiall R573402000 is a SP10T coaxial switch from the Ramses series, designed for high-frequency applications up to 18 GHz. It features an SMA interface and operates with a normally open configuration. The device requires a 12Vdc coil voltage within a supply range of 10.2V to 13V. It exhibits a maximum insertion loss of 0.7 dB at the test frequency and maintains a 50 Ohm impedance. The unit supports TTL diodes and utilizes pin terminals for connection. Operating temperatures range from -40°C to 85°C.

Feature Summary

• SP10T single-pole ten-throw switching architecture
• High-frequency operation up to 18 GHz
• Normally open contact configuration
• SMA connector interface

Applications

• RF signal routing in communication systems
• Test and measurement equipment
• Aerospace and defense radar systems
• Satellite ground station infrastructure

Procurement Notes

Verify component authenticity through authorized Radiall distributors or direct manufacturer channels. Confirm datasheet revisions match specific lot codes. Ensure environmental compliance documentation aligns with project requirements. Validate electrical specifications against current application loads. Request factory certification for critical aerospace or medical deployments.

Selection Notes

Select this model when ten distinct RF paths are required within a compact form factor. The 18 GHz bandwidth suits microwave applications. Verify that the 12Vdc control logic matches system power supplies. Consider the SMA interface compatibility with existing cabling. Evaluate thermal management needs given the 85°C upper operating limit.

Part Context

This component belongs to the Ramses family of coaxial switches by Radiall USA, Inc. The series emphasizes high reliability and low insertion loss for demanding RF environments. The SP10T topology allows complex signal distribution without multiple discrete switches. It serves as a specialized solution for multi-channel RF architectures requiring precise switching control.

Replacement Considerations

Cross-reference with other Ramses series variants for interface differences. Verify pinout compatibility before substituting similar SP10T models. Check frequency limits of alternative parts to ensure they meet the 18 GHz requirement. Confirm coil voltage specifications match existing control circuitry.
