R573F83625

Overview

The R573F83625 is a single-pole six-throw (SP6T) coaxial RF switch from the RAMSES series, manufactured by Radiall. It operates within a frequency range of DC to 26.5 GHz and features SMA connectors with a 50 Ohm impedance. The device utilizes latching technology with self-cut-off and auto-reset capabilities, powered by a 28Vdc TTL input. Designed for general-purpose applications, it offers high isolation and low insertion loss, suitable for demanding radio frequency environments.

Feature Summary

• Single-pole six-throw configuration supporting multiple signal paths
• Latching mechanism with self-cut-off and auto-reset functionality
• High-frequency operation up to 26.5 GHz using SMA interfaces

Applications

• Radio frequency test and measurement equipment
• Wireless communication infrastructure systems
• Electronic warfare and defense radar systems

Procurement Notes

Verify the specific datasheet version for the R573F83625 to confirm exact electrical tolerances and mechanical dimensions before integration. Ensure that the driving circuitry provides the required 28Vdc TTL signals compatible with the latching control inputs. Confirm compliance with RoHS3 standards if environmental regulations apply to the final assembly. Cross-reference connector types to ensure SMA compatibility with existing PCB layouts or cable assemblies.

Selection Notes

Select this component when a high-isolation SP6T switch is required for frequencies extending beyond standard microwave ranges. The latching feature reduces power consumption in steady states compared to non-latching alternatives. Verify that the 28Vdc control voltage aligns with available system power rails. Consider the SMA interface requirements for board space and mating cycle durability in the design phase.

Part Context

This part belongs to the RAMSES series of coaxial switches, which are designed for robust performance in harsh environments. The series typically includes various throw configurations and frequency ranges, utilizing advanced switching technologies to minimize signal degradation. The R573F83625 specifically addresses needs for multi-path routing at ultra-high frequencies.

Replacement Considerations

Check for direct substitutes within the R573 series offering different throw counts or frequency limits. Evaluate other RAMSES models for similar SMA packaging and latching characteristics. Ensure any replacement maintains the 28Vdc TTL control interface and 50 Ohm impedance matching.
