R591803440

RF Switches Overview

The R591803440 is a single-pole quadruple-throw (SP4T) coaxial RF switch manufactured by Radiall USA, Inc. It utilizes Subminiature Version A (SMA2.9) interface connectors and operates within a frequency range of 0 Hz to 40 GHz. The device features a normally open configuration with positive common diodes and requires a 28 Vdc control voltage. Constructed for high-frequency applications, it supports TTL logic inputs and employs double-row pin terminals for secure mounting.

RF Switches Feature Summary

• SP4T switching topology with normally open state
• Operates up to 40 GHz frequency range
• Positive common diode architecture
• 28 Vdc control voltage requirement

RF Switches Applications

• High-frequency signal routing in test and measurement equipment
• Telecommunications infrastructure switching
• Radar system signal distribution
• Aerospace and defense electronic systems

RF Switches Procurement Notes

Verify the specific SMA2.9 connector compatibility and 28 Vdc control requirements against your system design before procurement. Confirm that the positive common diode configuration aligns with your circuit logic. Ensure the module fits your PCB layout constraints regarding the double-row pin terminal spacing. Cross-reference the datasheet for precise mechanical dimensions and thermal management needs.

RF Switches Selection Notes

Select this component when an SP4T switching solution is required for frequencies extending to 40 GHz. The 28 Vdc drive voltage distinguishes it from lower-voltage alternatives. Consider the SMA2.9 interface size relative to available board space. Evaluate the positive common diode characteristic for its impact on signal isolation and insertion loss in your specific application environment.

RF Switches Part Context

This part belongs to Radiall's series of miniature coaxial switches designed for demanding RF environments. It complements other models like the R591802620, which offers SP6T configuration but differs in control voltage and port count. These components are engineered for reliability in compact form factors suitable for modern electronic systems requiring high-speed signal path reconfiguration.

RF Switches Replacement Considerations

Direct substitutes may include the R591802620 if additional ports are acceptable, though control voltages differ. Verify pinout compatibility and mechanical footprint before swapping. No identical SP4T 40GHz model with different voltage is explicitly listed in the provided data.
