R574403485

Overview

The R574403485 is a single-pole four-throw (SP4T) coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It utilizes SMA connectors and operates within a frequency range of 0 Hz to 18 GHz. The device features terminated ports and is designed for normally open operation. It requires a 28 Vdc control voltage and supports BCD or TTL input signals. The unit is constructed with gold-plated contacts and stainless steel housing, ensuring durability in demanding environments.

Feature Summary

• SP4T switching configuration with terminated output ports
• Operates up to 18 GHz frequency range
• Compatible with BCD and TTL control logic interfaces
• Ramses series construction for high reliability

Applications

• RF signal routing in test and measurement equipment
• Telecommunications infrastructure switching systems
• Aerospace and defense electronic warfare applications
• Automated RF testing setups requiring multi-port selection

Procurement Notes

Verify the specific control interface requirement, as the component supports both BCD and TTL signaling. Confirm that the 28 Vdc operating voltage aligns with your system power supply capabilities. Ensure the SMA connector type matches your existing cable assemblies. Check for any updated datasheet revisions that may affect pinout definitions or mechanical tolerances before finalizing integration.

Selection Notes

Select this component when an SP4T topology is required for frequencies extending to 18 GHz. The terminated ports simplify impedance matching in downstream circuits. Consider the Ramses series build quality for applications needing robust performance under vibration or thermal stress. Verify that the physical size constraints accommodate the switch dimensions and that the control voltage logic levels are compatible with your driving circuitry.

Part Context

This part belongs to Radiall's Ramses line of coaxial switches, known for high performance in microwave applications. The R574403485 specifically addresses needs for multi-path signal distribution in compact form factors.
