Overview
The R573493325 is a general-purpose SP3T coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It operates within a frequency range of 0 Hz to 18 GHz and features an SMA interface with 50 Ohm impedance. The device utilizes latching technology with self-cut-off functionality and auto-reset capabilities. Electrical specifications include a maximum insertion loss of 0.5 dB and a minimum isolation of 60 dB. It requires a 28 Vdc coil voltage and includes TTL diodes for control. The unit is equipped with indicators and connects via a D-sub connector.
Feature Summary
- SP3T configuration with latching mechanism and self-cut-off protection
- High-frequency operation up to 18 GHz with low insertion loss
- Integrated status indicators and D-sub connector interface
- Auto-reset functionality with TTL diode control
Applications
- RF signal routing in test and measurement equipment
- Telecommunications base station switching systems
- Aerospace and defense radar signal distribution
- Electronic warfare simulation environments
Procurement Notes
Verify the specific datasheet version for the R573493325 to confirm electrical tolerances and mechanical dimensions. Ensure compatibility with the required 28 Vdc control voltage and D-sub connector mating. Check for RoHS compliance status and environmental operating limits before integration. Confirm availability through authorized distributors as lead times may vary.
Selection Notes
Select this component when high-frequency switching up to 18 GHz is required with precise signal isolation. The latching feature reduces power consumption compared to non-latching alternatives. Consider the D-sub connector interface for system integration needs. Evaluate the 60 dB isolation specification against crosstalk requirements in dense RF architectures.
Part Context
This part belongs to the Ramses series of coaxial switches designed for demanding RF applications. It complements other SP3T and multi-pole variants in the Radiall portfolio. The series emphasizes reliability in aerospace and industrial sectors. Similar models may differ in pole count, frequency range, or connector type.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference data with manufacturer engineering support for equivalent performance characteristics.
