R573402435

RF Switches Overview

The R573402435 is a general-purpose SP4T coaxial RF switch from the Ramses series by Radiall USA, Inc. It operates within a frequency range of DC to 18 GHz and features a 50 Ohm impedance. The device utilizes SMA connectors for signal interfacing and is powered by a 12Vdc supply. It is designed as a normally open switch with diode protection. The component is supplied in bulk packaging.

RF Switches Feature Summary

• SP4T configuration supporting four distinct output positions
• Operational frequency coverage extending up to 18 GHz
• Normally open switching state architecture
• Integrated diode protection circuitry

RF Switches Applications

• High-frequency test and measurement instrumentation
• Wireless communication infrastructure systems
• Radar signal routing applications
• Electronic warfare subsystems

RF Switches Procurement Notes

Verify the specific connector interface type against project requirements, as datasheets indicate variations such as D-sub or Diodes connectors within this model family. Confirm that the 12Vdc operating voltage aligns with available power supplies. Ensure the SMA connector style matches the system cabling specifications before finalizing procurement orders.

RF Switches Selection Notes

Select this component when an SP4T topology is required for frequencies up to 18 GHz. The 12Vdc drive requirement distinguishes it from higher voltage variants like the 28Vdc models. Verify the specific connector termination style, as the Ramses series offers multiple interface options including D-sub and Diodes types depending on the exact suffix.

RF Switches Part Context

This part belongs to the Ramses series of high-performance coaxial switches. The series provides various configurations including SP4T and SP3T designs with different connector interfaces and drive voltages. The R573402435 specifically addresses needs for 18 GHz operation with a 12Vdc control signal.

RF Switches Replacement Considerations

The R573402430 is a documented substitute within the same Ramses series offering similar SP4T functionality at 18 GHz but utilizes a 12Vdc supply with different terminal pinning.
