R573403635

Overview

The R573403635 is an SP6T Ramses coaxial RF switch manufactured by Radiall USA, Inc. It operates within a frequency range of 0 Hz to 18 GHz and features a SMA interface with 50 Ohm impedance. The device utilizes normally open logic and requires a 28 Vdc control voltage via diode switching. It employs D-sub connector terminals for control signals and is designed for operation between -40°C and 85°C.

Feature Summary

• SP6T configuration providing six distinct output paths from a single input
• Ramses series architecture optimized for high-frequency signal routing
• Normally open switching logic ensuring default isolation state
• Diode-based control mechanism integrated with D-sub connector interface

Applications

• High-frequency signal distribution networks
• Test and measurement instrumentation systems
• Telecommunications base station architectures
• Electronic warfare and radar subsystems

Procurement Notes

Verify the specific control voltage requirements against system design specifications, as this model requires 28 Vdc. Confirm that the D-sub connector interface aligns with existing board layout constraints. Ensure thermal management strategies accommodate the specified operating temperature range of -40°C to 85°C during integration.

Selection Notes

Select this component when a six-way signal path is required within the 18 GHz bandwidth. The choice depends on the availability of 28 Vdc control lines and space for D-sub connectors. Consider the normally open state if default isolation is critical. Evaluate mechanical footprint compatibility against alternative SP6T modules before finalizing the design.

Part Context

This part belongs to the Ramses family of coaxial switches, which are engineered for robust performance in demanding RF environments. The series typically offers low insertion loss and high isolation characteristics. The R573403635 specifically adapts these capabilities for applications requiring multiple switched paths with standard SMA connectivity.
