R573423335

Overview

The R573423335 is an SP3T coaxial switch from the Ramses series by Radiall USA, Inc. It operates at frequencies up to 18 GHz with a 50 Ohm impedance and SMA interface. The device features latching actuation powered by 24V to 30V DC. Key electrical specifications include a maximum insertion loss of 0.50 dB, a VSWR of 1.5, and isolation ratings ranging from 70 dB to 80 dB depending on the frequency band (3-8 GHz, 8-12.4 GHz, and 12.4-18 GHz).

Feature Summary

• SP3T topology for signal routing across three output paths.
• Latching mechanism maintains state without continuous power.
• High-frequency operation supporting applications up to 18 GHz.
• SMA connector interface for standard coaxial integration.

Applications

• RF test and measurement instrumentation.
• Telecommunications base station signal distribution.
• Aerospace and defense electronic warfare systems.
• Automotive radar sensor testing setups.

Procurement Notes

Verify the specific datasheet revision and pinout configuration directly with Radiall USA, Inc. before procurement. Confirm that the latching voltage requirements align with the system power supply design. Ensure the SMA connector gender and mating compatibility match the existing harness infrastructure to prevent mechanical interference during installation.

Selection Notes

Select this component when a single-pole triple-throw switching function is required within the 18 GHz spectrum. The latching feature makes it suitable for environments where power conservation or state retention during outages is critical. Compare insertion loss and isolation metrics against other Ramses variants if higher frequency performance or different port configurations are needed for the specific application architecture.

Part Context

This part belongs to the Ramses family of high-performance coaxial switches designed for demanding RF environments. The series offers various topologies including SP4T and SP6T options with different connector types such as TNC and D-sub. The R573423335 specifically utilizes the SMA interface and latching technology to provide reliable signal path management in compact form factors.

Replacement Considerations

Consider the R573403315 for non-latching SP3T applications requiring 28VDC actuation. For SP4T configurations, evaluate the R573403400 model. Verify that any substitute maintains the 18 GHz frequency limit and compatible SMA interface geometry to ensure seamless integration without redesigning the PCB layout or cabling.

FAQ

What is the isolation specification for the R573423335?
