Overview
The Radiall R573433445 is an SP4T coaxial switch from the Ramses series, operating up to 18 GHz with a 50 Ohm impedance. It features SMA connectors and positive common diodes. Key electrical parameters include a VSWR of 1.5:1, insertion loss of 0.5 dB, and isolation of 60 dB. The device uses 28 VDC coil voltage and offers a mechanical life of 5,000,000 cycles. It operates between -40°C and +85°C.
Feature Summary
- SP4T configuration with positive common diodes for signal routing
- Latching mechanism with integrated position indicators
- High-frequency performance up to 18 GHz
- SMA connector interface for standard coaxial integration
Applications
- RF signal distribution in test and measurement equipment
- Telecommunications base station switching networks
- Aerospace and defense radar systems
- Satellite communication ground stations
Procurement Notes
Verify current availability directly with Radiall USA, Inc., as distributor listings may be inconsistent or outdated. Confirm RoHS compliance status through official documentation before procurement. Ensure the specific ordering suffix matches the required connector type and latching indicator configuration. Request factory verification for lifecycle status if integrating into long-term production designs.
Selection Notes
Select this component when an SP4T coaxial switch with latching functionality and SMA interfaces is required. The 18 GHz frequency range suits high-speed RF applications. Verify that the 28 VDC control voltage aligns with system power supplies. Consider the 5,000,000 cycle life for durability requirements. Compare against non-latching variants if power consumption during static states is a critical constraint.
Part Context
This part belongs to the Ramses series of coaxial switches by Radiall. The series is designed for high-reliability RF applications requiring precise signal routing. The R573433445 specifically denotes the SP4T configuration with SMA connectors and latching indicators. It is distinct from other Ramses variants that may offer different pole counts, connector types, or non-latching mechanisms.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided source data. Consult Radiall technical support for direct replacements or pin-compatible alternatives within the Ramses family.
