R573403640

Overview

The R573403640 is a single-pole six-throw (SP6T) radio frequency switch manufactured by Radiall USA, Inc. It operates within a frequency range of 0 to 18 GHz and maintains a characteristic impedance of 50 Ohms. The device features normally open contacts and utilizes positive common pin terminals for connection. Designed for general-purpose RF applications, it supports switching signals across multiple paths with high isolation capabilities inherent to its SP6T configuration.

Feature Summary

• Single-pole six-throw switching architecture
• Operates up to 18 GHz frequency range
• Normally open contact configuration
• Positive common pin terminal interface

Applications

• RF signal routing in communication systems
• Test and measurement equipment switching
• Phased array antenna beamforming networks
• General purpose RF signal path selection

Procurement Notes

Verify the specific datasheet version and electrical characteristics directly from Radiall official documentation before integration. Confirm that the package type and pinout match the PCB layout requirements. Ensure operating conditions remain within the specified voltage and current limits to maintain reliability and prevent damage to the switch components during deployment.

Selection Notes

Select this component when a single input must be routed to one of six distinct output paths at frequencies up to 18 GHz. The SP6T topology is suitable for complex signal distribution tasks. Consider the normally open state and positive common terminal design for circuit compatibility. Evaluate insertion loss and isolation specifications against system requirements to ensure adequate signal integrity across all active channels.

Part Context

This part belongs to the Radiall R573 series of RF switches. The series includes various configurations such as SP3T and SP4T variants. These components are designed for high-frequency applications requiring reliable signal switching. The R573403640 specifically provides six output paths, offering greater flexibility than lower-throw counterparts in multi-channel RF architectures.

Replacement Considerations

The R573403610 is a documented substitute within the same product family. Both parts share the SP6T topology and 18 GHz frequency range. Verify pin compatibility and electrical parameters before substitution. Other R573 series models may offer different throw counts but serve similar functional roles.
