R573453405

RF Switches Overview

The R573453405 is a SP4T coaxial switch from the Ramses series by Radiall USA, Inc. It operates with an SMA interface and supports frequencies up to 18 GHz. The device features a latching mechanism controlled by a 28 Vdc supply and utilizes a D-sub connector for control signals. Constructed with positive common diode technology, it ensures normally open functionality. The unit maintains a 50 Ohm impedance and is packaged in bulk for integration into RF systems.

RF Switches Procurement Notes

Verify component authenticity through authorized Radiall distributors or direct manufacturer channels. Confirm datasheet revisions and specific lot traceability requirements before procurement. Ensure storage conditions align with manufacturer specifications to maintain performance integrity. Cross-reference part numbers with official Radiall documentation to avoid counterfeit components.

RF Switches Selection Notes

Select this model when a latching SP4T switch is required for frequencies up to 18 GHz. The D-sub control interface suits applications needing discrete control lines rather than integrated drivers. Verify that the 28 Vdc latching voltage aligns with available system power supplies. Consider thermal management requirements based on insertion loss characteristics at operating frequencies.

RF Switches Part Context

This component belongs to the Ramses family of high-performance coaxial switches designed for demanding RF environments. The series emphasizes reliability and precise signal routing in complex multi-port configurations. Integration into larger systems typically involves connecting the SMA ports to transmission lines and the D-sub port to control logic.

RF Switches Replacement Considerations

Consult Radiall technical support for verified substitute part numbers within the Ramses series. Ensure replacement units match the SP4T topology, SMA interface, and latching control requirements. Validate frequency range and impedance compatibility before substitution.
