Overview
The R573402305 is a general-purpose SP3T coaxial RF switch from the Ramses series by Radiall USA, Inc. It operates at a frequency range of 18 GHz with a 50 Ohm impedance. The device features an SMA connector interface and utilizes a 12 Vdc coil voltage for actuation. Key electrical specifications include a maximum insertion loss of 0.5 dB, a VSWR of 1.5:1, and isolation of 60 dB. It is designed as a normally open switch with a positive common configuration.
Feature Summary
- SP3T switching topology for signal routing
- High-frequency operation up to 18 GHz
- SMA connector interface for reliable connection
- Normally open configuration with positive common
Applications
- RF test and measurement equipment
- Wireless communication systems
- Aerospace and defense radar applications
Procurement Notes
Verify the specific ordering suffix to confirm connector type and voltage requirements. Ensure compatibility with system impedance and frequency ranges. Confirm RoHS compliance status if required. Check lead times as availability may vary. Validate datasheet parameters against application needs before purchase.
Selection Notes
Select this component for applications requiring high-frequency switching up to 18 GHz. Consider the SP3T configuration for single-pole triple-throw routing needs. Evaluate the 12 Vdc drive requirement against available power supplies. Assess insertion loss and isolation specs for signal integrity requirements in the target RF chain.
Part Context
This part belongs to the Ramses series of coaxial switches from Radiall. The series offers various configurations including SP3T and SP4T options with different connector types like SMA and 2.9mm. These switches are designed for high-reliability applications in demanding environments.
Replacement Considerations
Cross-reference with other Ramses series parts such as R573403315 or R573402345 for similar functionality. Verify that substitute parts match the 18 GHz frequency limit and SMA connector interface. Ensure electrical parameters like insertion loss and VSWR meet or exceed original specifications.
