R573402520

Overview

The R573402520 is a single-pole five-throw (SP5T) coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It operates with SMA connectors and supports frequencies up to 18 GHz. The device features a normally open configuration and utilizes 12 VDC coil voltage for actuation. Electrical specifications include a characteristic impedance of 50 Ohms, a maximum Voltage Standing Wave Ratio (VSWR) of 1.5, and an insertion loss of 0.5 dB. Isolation between ports is rated at 60 dB. The unit employs pin terminals for soldering and is packaged in bulk.

Feature Summary

• Single-pole five-throw switching architecture for signal routing
• High-frequency operation capability up to 18 GHz
• Normally open contact configuration for default state management
• Low insertion loss and high isolation performance

Applications

• RF signal distribution networks
• Test and measurement instrumentation
• Telecommunications base stations
• Aerospace and defense radar systems

Procurement Notes

Verify the specific datasheet version and electrical tolerances directly with Radiall or authorized distributors before procurement. Confirm that the 12 VDC TTL drive requirements align with the system control logic. Ensure the SMA connector interface matches the PCB footprint and mating hardware specifications. Validate compliance with RoHS and REACH regulations as required by the target application environment.

Selection Notes

Select this component when a single input must be routed to one of five distinct output paths within an 18 GHz bandwidth. The SP5T topology is suitable for applications requiring flexible signal path selection. Consider the 12 VDC power requirement for driver circuit design. The Ramses series offers compact form factors ideal for space-constrained RF modules. Evaluate thermal management needs based on the power handling capabilities defined in the official technical data sheet.

Part Context

This part belongs to the Ramses family of coaxial switches, designed for high-performance RF applications. The series emphasizes low loss and high reliability in microwave frequency ranges. Radiall manufactures these components using precision engineering techniques to ensure consistent electrical performance across the operating temperature range. The Ramses line is widely recognized in professional RF engineering sectors.

Replacement Considerations

Cross-reference with other SP5T SMA switches from Radiall or compatible manufacturers if supply constraints exist. Verify that substitute parts match the 18 GHz frequency limit, 50 Ohm impedance, and 12 VDC drive voltage. Ensure mechanical dimensions and pin terminal configurations are compatible with existing PCB layouts. Consult official substitution lists from Radiall for validated alternatives.
