Overview
The R574412800 is a general-purpose RF switch IC from the RAMSES series, manufactured by Radiall USA, Inc. It features an SP8T circuit configuration with SMA terminated connectors. The device operates within a frequency range of DC to 18GHz and maintains a nominal impedance of 50 Ohms across all ports. It requires a supply voltage between 24V and 30V. The unit is housed in a module package with SMA connectors and functions reliably within an operating temperature range of -40°C to 85°C.
Feature Summary
- SP8T switching topology for multi-path signal routing
- SMA terminated connector interface for standardized transmission lines
- RAMSES series design optimized for high-frequency applications up to 18GHz
Applications
- RF signal distribution networks
- Test and measurement instrumentation
- Telecommunications base station equipment
Procurement Notes
Verify the specific datasheet version for the R574412800 to confirm current manufacturing status and environmental compliance details. Ensure that the required supply voltage and interface compatibility match the system design requirements before procurement. Cross-reference the manufacturer's official documentation for any updates regarding lead times or component availability.
Selection Notes
Select this component when an eight-port RF switching solution is required for frequencies up to 18GHz. The 50-ohm impedance matching ensures minimal signal reflection in standard transmission line environments. Consider the SMA termination style for ease of integration into existing RF infrastructure requiring terminated ports.
Part Context
This part belongs to the RAMSES series of RF switches, designed for robust performance in demanding radio frequency environments. The series offers various port configurations, with this specific model providing an eight-channel switching capability. It is engineered to support high-frequency operations while maintaining signal integrity through precise impedance control.
Replacement Considerations
The R574G13345 is a documented substitute offering SP3T functionality within the same RAMSES series. Verify that the reduced port count meets the application requirements and that the SMA interface remains compatible.
