Overview
The R573483420 is an SP4T coaxial switch from the Ramses series by Radiall USA, Inc. It operates up to 18 GHz with a 50 Ohm impedance. The device features SMA connectors and solder terminals. It functions as a normally open switch controlled by 28 VDC or TTL signals. Key electrical specifications include a VSWR of 1.5, insertion loss of 0.5 dB, and isolation of 60 dB. The component is supplied in bulk packaging.
Feature Summary
- SP4T switching configuration for signal routing
- High-frequency operation up to 18 GHz
- Latching mechanism for stable state retention
- Compatible with 28 VDC or TTL control inputs
Applications
- RF test and measurement equipment
- Telecommunications base stations
- Aerospace and defense radar systems
- Satellite communication ground stations
Procurement Notes
Verify the specific control logic requirement (28 VDC vs. TTL) against the datasheet before ordering, as variants exist within the Ramses family. Confirm that the SMA connector orientation and terminal type match the PCB layout requirements. Ensure environmental conditions align with the specified operating temperature range. Cross-reference the exact part number suffix to guarantee compatibility with existing system designs.
Selection Notes
Select this component when high-frequency switching up to 18 GHz is required with low insertion loss. The latching feature reduces power consumption compared to non-latching alternatives. Verify that the SMA interface meets the system's interconnect needs. Consider the bulk packaging format for assembly processes. Ensure the control voltage matches the available drive circuitry.
Part Context
This part belongs to the Ramses series of coaxial switches designed for demanding RF applications. It represents a solid-state solution for signal path management in high-performance electronic systems. The series is known for reliability and consistent electrical performance across wide frequency bands.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source material. Consult manufacturer documentation for direct equivalents or pin-compatible alternatives.
