R573483385

Overview

The R573483385 is a high-frequency RF relay from the Ramses series, manufactured by Radiall USA, Inc. It features an SMA interface and operates up to 18 GHz with a 50-ohm impedance. The component is an SP3T (Single Pole Triple Throw) switch that utilizes latching technology for power efficiency. It supports self-cut-off functionality and auto-reset capabilities. The device is designed for 28Vdc coil voltage operation and interfaces via TTL or BCD logic signals. It includes integrated diodes and connects through a D-sub connector.

Feature Summary

• SP3T switching configuration with latching mechanism
• High-frequency performance up to 18 GHz
• Self-cut-off and auto-reset operational modes
• D-sub connector interface for control signals

Applications

• RF signal routing in communication systems

Procurement Notes

Verify the specific datasheet version for the R573483385 to confirm exact pinout assignments for the D-sub connector and TTL/BCD logic levels. Ensure compatibility with the 28Vdc coil voltage requirements of your control circuitry. Cross-reference the self-cut-off specifications against your system's thermal management design to prevent overheating during continuous operation.

Selection Notes

Select this component when a reliable, high-frequency SP3T switch is required for applications demanding low insertion loss and high isolation. The latching feature makes it suitable for systems where power conservation is critical during static states. Verify that the SMA interface type matches your existing cable assemblies and that the D-sub control interface integrates correctly with your driver electronics.
