R573432240

Overview

The Radiall R573432240 is a general-purpose SP12T coaxial switch from the RAMSES series, designed for RF applications up to 12.4 GHz. It features SMA connectors and operates with a positive common configuration. The device utilizes latching technology controlled by a 12V DC supply within an input voltage range of 10.2V to 13V. Key electrical specifications include a maximum insertion loss of 0.6 dB and a minimum isolation of 60 dB. It supports a frequency range of 0 Hz to 12.4 GHz with a 50 Ohm impedance and maintains an operating temperature range of -40°C to 85°C.

Feature Summary

• SP12T single-pole twelve-throw switching architecture
• RAMSES series high-isolation design
• SMA connector interface
• Positive common contact configuration

Applications

• RF signal routing in test and measurement equipment
• Telecommunications infrastructure switching
• Aerospace and defense radar systems
• Electronic warfare signal processing

Procurement Notes

Verify component authenticity through authorized Radiall distributors or direct manufacturer channels. Confirm datasheet revisions and RoHS compliance status prior to integration. Ensure storage conditions meet specified environmental limits to preserve connector integrity and switching performance over the operational lifespan.

Selection Notes

Select this model when high channel count (12 outputs) and wide bandwidth (up to 12.4 GHz) are required. The latching mechanism reduces power consumption during state retention compared to continuous energization. Verify that the system control logic can provide the necessary 12V DC latching pulses and that the physical SMA interface matches existing board layouts.

Part Context

This component belongs to the Radiall RAMSES family of coaxial switches, which are engineered for robust performance in demanding RF environments. The series offers various throw configurations and connector types, providing scalable solutions for complex signal distribution networks requiring high reliability and low signal degradation.

Replacement Considerations

Cross-reference with other Radiall RAMSES models such as R573402430 for different throw counts. Ensure substitute parts maintain compatible SMA interfaces and 12V DC latching requirements. Verify that alternative SP12T switches offer equivalent 60 dB isolation and 0.6 dB insertion loss specifications.
