R573403015

Overview

The Radiall R573403015 is an SP10T coaxial switch from the RAMSES series, designed for high-frequency applications up to 18 GHz. It features a normally open configuration with positive common control logic and operates on a 28 VDC coil voltage. The component utilizes SMA connectors and includes a D-sub connector interface for command signals. Constructed with 50 Ohm impedance, it provides robust signal routing in complex RF systems requiring multiple path selection capabilities.

Feature Summary

• SP10T switching topology enabling connection of one common port to ten distinct output paths
• RAMSES series architecture optimized for high-reliability microwave and radio frequency environments
• Positive common actuation logic ensuring defined default state without continuous power retention

Applications

• Complex RF test and measurement instrumentation requiring multi-channel signal routing
• Telecommunications base station infrastructure for antenna or feed line switching
• Aerospace and defense electronic warfare systems demanding high-isolation signal distribution

Procurement Notes

Verify manufacturing status directly with Radiall USA, Inc., as availability may vary. Confirm specific ordering suffixes to ensure correct connector type and pinout configuration. Request current datasheets to validate electrical parameters against system requirements before integration.

Selection Notes

Select this model when ten distinct output paths are required from a single input source within the 18 GHz bandwidth. Ensure the design supports 28 VDC control voltage and accommodates the physical footprint of the D-sub connector interface. Evaluate isolation and insertion loss specifications against link budget requirements.

Part Context

This component belongs to the RAMSES family of coaxial switches, which are engineered for demanding industrial and military applications. The series offers various configurations including SPDT through SP10T options across different connector interfaces like SMA and TNC, providing scalable solutions for RF signal management.

Replacement Considerations

Cross-reference with other RAMSES series models such as R573403005 for SP10T variants or R573403315 for SP3T configurations if fewer ports suffice. Verify mechanical compatibility and control logic alignment before substituting.
