R573402345

Overview

The R573402345 is an SP3T coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It operates at a maximum frequency of 18 GHz with a 50 Ohm impedance. The device features a normally open configuration and utilizes positive common diodes for switching. It is designed for board-level integration using D-sub connector terminals and requires a 12Vdc actuation voltage.

Feature Summary

• SP3T single-pole triple-throw topology
• Normally open switching state
• Positive common diode technology
• D-sub connector interface

Applications

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

Procurement Notes

Verify the specific datasheet revision to confirm terminal pinout compatibility with your PCB layout. Ensure the driving circuit provides stable 12Vdc power. Confirm that the D-sub connector type matches your system requirements before finalizing procurement.

Selection Notes

Select this component when an SP3T configuration is required within the 18 GHz bandwidth. The normally open state and diode-based switching mechanism are key differentiators. Verify that the D-sub interface fits the available space and mechanical constraints of the assembly.
