Overview
The R570453100 is a SPDT coaxial switch from the RAMSES series by Radiall USA, Inc. It operates within a frequency range of DC to 18 GHz and utilizes SMA connectors. The device features latching functionality with self-cut-off capability, controlled via TTL diodes at 28 Vdc. Key electrical parameters include an insertion loss of 0.35 dB maximum and a 50 Ohm impedance. This component is designed for high-frequency RF applications requiring reliable signal routing.
Feature Summary
- SPDT configuration with SMA interface
- Latching mechanism with self-cut-off operation
- TTL diode control at 28 Vdc
- Low insertion loss performance
Applications
- RF signal routing in communication systems
- Test and measurement equipment
- Aerospace and defense radar systems
- Satellite ground station infrastructure
Procurement Notes
Verify the specific datasheet version and mechanical dimensions against your PCB layout requirements. Confirm that the TTL diode control logic matches your system's voltage levels. Ensure SMA connector compatibility with existing cable assemblies. Check for any environmental qualification certifications if operating in extreme conditions. Validate supply chain authenticity through authorized distributors.
Selection Notes
Select this model when SPDT switching is required up to 18 GHz. Consider the latching feature for power efficiency in static states. Verify that the 0.35 dB insertion loss meets system budget constraints. Ensure the 28 Vdc control voltage is available in the design. Compare with non-latching variants if continuous power consumption is a concern.
Part Context
This component belongs to the RAMSES family of coaxial switches, known for high reliability in harsh environments. It is part of Radiall's portfolio of RF interconnect solutions. The series includes various configurations for different frequency ranges and connector types. It is commonly used in critical infrastructure where signal integrity is paramount.
Replacement Considerations
Check for direct substitutes within the RAMSES series with compatible pinouts. Verify equivalent frequency ratings and insertion loss specifications. Ensure control voltage and logic compatibility. Consult manufacturer cross-reference guides for approved alternatives.
