R573102425

Overview

The Radiall R573102425 is an SP4T coaxial switch from the Ramses series, designed for high-frequency applications up to 12.4 GHz. It features a normally open configuration with a 12 Vdc coil voltage and utilizes a D-sub connector interface. The component operates at a standard 50 Ohm impedance. Key electrical specifications include a maximum insertion loss of 0.5 dB, a typical VSWR of 1.5, and isolation of 60 dB. The device is housed in a bulk package and is non-illuminated.

Feature Summary

• SP4T switching topology within the Ramses series
• Low PIM design characteristics
• D-sub connector interface

Applications

• RF signal routing in communication systems
• Test and measurement equipment
• Aerospace and defense radar systems

Procurement Notes

Verify availability directly with Radiall or authorized distributors as stock status may vary. Confirm that the D-sub connector variant matches system integration requirements. Ensure compliance with RoHS standards before procurement. Request official datasheets for precise electrical validation.

Selection Notes

Select this model for applications requiring SP4T switching at frequencies up to 12.4 GHz. The 12 Vdc drive voltage and D-sub interface are critical selection criteria. Compare against R573102405LP if low PIM performance is required. Verify pinout compatibility with existing control circuitry.

Part Context

Part of the Ramses family of coaxial switches by Radiall. Similar models include R573102405LP and R573103430LP. These components share similar frequency ranges but differ in connector types and specific electrical optimizations like PIM reduction.

Replacement Considerations

R573102405LP is a documented alternative within the same series. Verify connector type and electrical parameters match before substitution.
