Overview
The R573403805 is a general-purpose RF switch IC manufactured by Radiall USA, Inc. It features an SP8T configuration with SMA connectors and operates up to 18 GHz. The device maintains a 50 Ohm impedance and exhibits a maximum insertion loss of 0.6 dB. Designed for broad frequency applications ranging from 0 Hz to 18 GHz, it serves as a reliable component for signal routing in high-frequency electronic systems.
Feature Summary
- SP8T single-pole eight-throw switching architecture
- SMA connector interface for standardized integration
- Operational frequency range extending to 18 GHz
- Low insertion loss characteristics for signal integrity
Applications
- General-purpose RF signal routing
- Test and measurement equipment
- Telecommunications infrastructure
- Aerospace and defense systems
Procurement Notes
Verify the specific datasheet version and RoHS compliance status directly with Radiall or authorized distributors before procurement. Confirm that the SMA connector type and SP8T configuration align precisely with system requirements. Ensure environmental ratings meet operational conditions. Cross-reference part numbers to avoid confusion with similar Ramses series variants.
Selection Notes
Select this component when an SP8T configuration is required within the 18 GHz bandwidth. The 50 Ohm impedance matches standard RF transmission lines. Consider the SMA interface compatibility with existing board layouts. Evaluate insertion loss specifications against system sensitivity requirements. Verify thermal management needs for continuous operation at specified frequencies.
Part Context
This component belongs to the Ramses series of coaxial switches produced by Radiall. The series includes various configurations such as SP3T, SP4T, SP6T, and SP10T models. These switches are designed for high-performance applications requiring reliable signal switching in demanding environments. The Ramses line emphasizes durability and consistent electrical performance across wide frequency ranges.
Replacement Considerations
Direct substitutes include other Ramses series models like R573403315 (SP3T) or R573403005 (SP10T), provided the throw count adjustment is acceptable. Verify connector type and frequency limits match application needs. No identical SP8T replacement is confirmed in public documentation.
