Overview
The R574413330 is a terminated SP3T coaxial switch from the RAMSES series, manufactured by Radiall USA, Inc. It operates within a frequency range of DC to 18 GHz and features SMA connectors. The device has a 50 Ohm impedance and requires a supply voltage of 24V to 30V. It is designed for general RF applications with a typical insertion loss of 0.5 dB maximum and isolation of 60 dB minimum.
Feature Summary
- SP3T topology for signal routing
- Terminated module design with integrated SMA connectors
- High-frequency operation up to 18 GHz
- Low insertion loss and high isolation characteristics
Applications
- RF test and measurement equipment
- Telecommunications base stations
- Aerospace and defense radar systems

Procurement Notes
Verify the specific datasheet revision and electrical tolerances against your system requirements before procurement. Confirm that the 24V to 30V supply voltage aligns with your power infrastructure. Ensure SMA connector compatibility with existing cabling. Check for any environmental certifications required for your deployment location. Validate lead times as these are specialized components.
Selection Notes
Select this component when an SP3T switching solution is required for frequencies up to 18 GHz. The terminated design simplifies integration by eliminating the need for external housing or connector assembly. Consider the 50 Ohm impedance match for standard RF systems. Evaluate the thermal performance if operating at elevated temperatures within the specified range.
Part Context
This part belongs to the RAMSES family of coaxial switches, which are known for high reliability in demanding environments. The R574413330 specifically utilizes SMA interfaces, distinguishing it from N-type or 2.4mm variants within the same product line. It represents a solid-state switching solution for microwave applications.
Replacement Considerations
Direct substitutes may include other RAMSES series models with different connector types such as R574G13345 (SMA) or R574103300 (N-type). Verify pinout and voltage requirements when cross-referencing. No other direct equivalent part numbers are publicly confirmed for this exact specification.
