R574312535

Overview

The R574312535 is a single-pole five-throw (SP5T) terminated RF switch from the RAMSES series, manufactured by Radiall USA, Inc. It operates with an SMA connector interface and supports frequencies up to 3 GHz. The device features a latching mechanism controlled by TTL diodes at 28Vdc. Key electrical specifications include a minimum isolation of 60 dB and a maximum insertion loss of 0.5 dB. It maintains a 50 Ohm impedance and functions within a temperature range of -40°C to 85°C.

Feature Summary

• SP5T switching configuration for signal routing
• Terminated design with integrated control logic
• High isolation performance for signal integrity
• SMA connector interface for standard integration

Applications

• Test and measurement instrumentation
• Wireless communication base stations
• Aerospace and defense radar systems
• RF signal distribution networks

Procurement Notes

Verify the specific ordering suffix to confirm the exact termination style and control voltage requirements. Ensure compatibility with existing TTL control signals. Confirm that the SMA connector type matches the system board layout. Check for any environmental certifications required for the deployment location. Validate the lead time availability directly with the manufacturer or authorized distributors.

Selection Notes

Select this component when a reliable SP5T switching solution is needed for frequencies up to 3 GHz. Consider the terminated design for simplified PCB layout compared to bare switches. Evaluate the 60 dB isolation requirement against system noise floor needs. Ensure the 28Vdc TTL control interface aligns with the host controller's output capabilities. Verify the operating temperature range meets the environmental conditions of the application.
