R573J13420

Overview

The R573J13420 is a general-purpose RF coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It features an SP4T circuit configuration with a 50 Ohm impedance and operates up to 50 GHz. The device utilizes a normally open state and is powered by a 24V to 30V DC supply. It employs TTL diodes for control and includes indicator functionality. The unit is housed in a module package with pin terminals.

Feature Summary

• SP4T switching topology supporting high-frequency applications
• Normally open contact configuration for signal routing
• Integrated indicator system for status monitoring
• TTL diode control interface for digital actuation

Applications

• High-frequency test and measurement equipment
• Telecommunications infrastructure signal routing
• Aerospace and defense radar systems
• Semiconductor wafer probe stations

Procurement Notes

Verify the specific Ramses series datasheet for the R573J13420 to confirm exact electrical tolerances and mechanical dimensions. Ensure compatibility with the required 24V-30V DC supply voltage and TTL logic levels. Confirm that the 2.4mm connector interface matches the system design requirements. Check current availability status as lead times may vary significantly for this component type.

Selection Notes

Select this component when a high-isolation, high-frequency SP4T switch is required within the Ramses product line. The 50 GHz frequency rating distinguishes it from lower-frequency variants like the R573312320 or R574G13420. Consider the module package style and pin terminal termination method against PCB layout constraints. Verify that the normally open state aligns with the default system power-up requirements.

Part Context

This part belongs to the Ramses family of multithrow coaxial switches, which offers extensive configuration options. The R573J13420 represents a high-performance variant within the R573 series, designed for demanding RF environments. It shares architectural similarities with other Ramses models but differs in frequency range and connector type, specifically utilizing a 2.4mm interface compared to SMA alternatives found in other series members.

Replacement Considerations

Direct substitutes within the Ramses series include the R574G13420 (18 GHz) or R573432420 (18 GHz), though these offer lower frequency performance. No identical 50 GHz replacement is confirmed in the provided data. Verify mechanical footprint and pinout compatibility before substituting with any other SP4T coaxial switch.
