R570942040

Overview

The R570942040 is a single-pole double-throw (SPDT) coaxial RF switch manufactured by Radiall USA, Inc. It operates within a frequency range of 0 Hz to 2.5 GHz and features a latching mechanism with indicator functionality. The device supports 12 Vdc coil voltage and utilizes TTL logic for control. Key electrical specifications include a maximum insertion loss of 0.3 dB and a minimum isolation of 70 dB. It is designed for chassis mounting and employs pin terminals for circuit integration.

Feature Summary

• Single-pole double-throw topology for signal routing
• Latching mechanism with integrated status indicators
• TTL logic control interface
• Chassis mount construction

Applications

• RF signal switching in test and measurement equipment
• Telecommunications infrastructure signal routing
• Aerospace and defense radar systems
• Electronic warfare signal processing units

Procurement Notes

Verify the specific datasheet version and mechanical drawings prior to procurement. Confirm that the 12 Vdc coil voltage requirement aligns with your system power supply architecture. Ensure chassis mounting provisions match your enclosure design constraints. Validate that the TTL logic levels are compatible with your control interface signals to prevent operational errors.

Selection Notes

Select this component when a latching SPDT switch is required for frequencies up to 2.5 GHz. Consider the 0.3 dB insertion loss and 70 dB isolation limits against your system budget. Evaluate the chassis mount form factor against available panel space. Verify compatibility with 12 Vdc power supplies and TTL control signals before finalizing the design.

Part Context

This part belongs to the Ramses series of coaxial switches from Radiall. The series is characterized by high-performance RF switching capabilities for demanding applications. The R570942040 variant specifically integrates latching functionality and visual indicators, distinguishing it from non-latching or unlatched counterparts within the broader product family.

Replacement Considerations

Consult official Radiall documentation for qualified substitute part numbers. Verify that any replacement maintains the 0 Hz to 2.5 GHz frequency range, 12 Vdc coil voltage, and TTL control interface. Ensure mechanical dimensions and chassis mounting requirements remain compatible with existing assembly designs.
