R573493420

Overview

The R573493420 is a single-pole four-throw (SP4T) RF switch manufactured by Radiall USA, Inc. It operates within a frequency range of 0 Hz to 18 GHz and maintains a characteristic impedance of 50 Ohms. This component functions as an integrated circuit designed for routing radio frequency signals from one input to four selectable outputs. The device supports general-purpose applications requiring precise signal path selection in high-frequency environments.

Feature Summary

• Single-pole four-throw configuration for flexible signal routing
• Operates across a wide frequency spectrum up to 18 GHz
• Designed for general-purpose RF switching applications

Applications

• Signal routing in test and measurement equipment
• RF signal distribution systems
• Telecommunications infrastructure components

Procurement Notes

Verify the specific datasheet version with the manufacturer before procurement, as specifications may vary. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure that the required lead time aligns with project schedules, noting standard delivery periods may apply. Cross-reference part numbers carefully to avoid confusion with similar models in the Ramses series.

Selection Notes

Select this component when a compact SP4T solution is required for frequencies up to 18 GHz. Consider the 50 Ohm impedance match for compatibility with standard RF systems. Evaluate thermal management requirements if operating near maximum frequency limits. Verify interface compatibility with existing PCB layouts and control logic before integration into the design.
