R574312625

Overview

The R574312625 is a single-pole six-throw (SP6T) RF coaxial switch manufactured by Radiall USA, Inc. It operates within a frequency range of DC to 3 GHz and maintains a system impedance of 50 Ohms. The device utilizes SMA connectors for signal interfacing and requires a coil voltage of 12 VDC for operation. Key electrical specifications include an insertion loss of 0.2 dB maximum, a voltage standing wave ratio (VSWR) of 1.2, and isolation of 80 dB minimum. The unit functions as a normally open switch with TTL control compatibility.

Feature Summary

• Provides high-isolation signal routing across six output paths using electromechanical switching technology
• Ensures low signal attenuation and stable impedance matching for precision RF applications
• Features robust SMA connector interfaces for reliable coaxial cable integration

Applications

• RF signal distribution networks requiring multi-path selection
• Test and measurement instrumentation systems
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific datasheet version and mechanical drawings before integration. Confirm that the 12 VDC coil voltage requirement aligns with the host system power supply capabilities. Ensure SMA mating connectors are compatible with the specified interface standards. Check for any environmental certifications required for the intended deployment location.

Selection Notes

Select this component when a single input must be routed to one of six distinct outputs within the 3 GHz bandwidth. The SP6T topology offers higher channel density than dual-pole alternatives. Consider the physical module size and SMA connector orientation during PCB or chassis layout planning to ensure adequate clearance for cabling.

Part Context

This part belongs to the Ramses series of coaxial switches from Radiall. The series is designed for general-purpose RF switching applications requiring high performance and reliability. The R574312625 variant specifically targets lower frequency operations up to 3 GHz compared to higher-frequency models in the same family.

Replacement Considerations

Consult official Radiall documentation for verified substitute part numbers. Cross-reference technical parameters such as frequency range, isolation levels, and connector types to ensure functional equivalence.
