R573402440

Overview

The R573402440 is a general-purpose SP4T RF switch module manufactured by Radiall USA, Inc. It operates within a frequency range of 0Hz to 18GHz and features a 50 Ohm impedance. The component provides a minimum isolation of 60dB and maintains a maximum insertion loss of 0.5dB at the test frequency of 18GHz. Designed for robust performance in high-frequency applications, this module integrates switching capabilities into a compact form factor suitable for various RF system architectures.

Feature Summary

• SP4T configuration for signal routing
• Broadband operation up to 18GHz
• High isolation performance
• Low insertion loss characteristics

Applications

• RF test and measurement equipment
• Wireless communication systems
• Aerospace and defense radar systems

Procurement Notes

Verify current availability and lead times directly with authorized distributors or the manufacturer, as stock levels fluctuate. Confirm that the specific module package matches your design requirements. Ensure compliance with relevant export control classifications and environmental standards before finalizing procurement orders for production use.

Selection Notes

Select this model when an SP4T topology is required for frequencies extending to 18GHz. Prioritize units offering 60dB isolation and low insertion loss for critical signal integrity. Evaluate thermal management needs within the module enclosure. Compare against alternative series if higher channel counts or different connector types are necessary for the specific application environment.

Part Context

This part belongs to Radiall's RF Switch IC line, specifically designed for general-purpose applications. It complements other modules like the R591303440, which offers similar functionality but operates at lower frequencies up to 6GHz. The R573402440 extends the bandwidth capability, providing engineers with options for higher-frequency signal routing solutions within the same product family ecosystem.

Replacement Considerations

Consider the R591303440 for applications requiring SP4T switching but operating below 6GHz. Verify mechanical compatibility and pinout alignment before substitution. Ensure that the reduced frequency range of potential substitutes does not compromise system performance requirements in the target deployment scenario.
