R573803320

Overview

The Radiall R573803320 is an SP3T coaxial switch from the Ramses series, designed for high-frequency applications up to 40 GHz. It features SMA 2.9 connectors and operates with a normally open configuration. The device utilizes TTL control signals and includes suppression diodes for protection. Key electrical parameters include a maximum insertion loss of 0.5 dB and isolation of 60 dB. It requires a 28 VDC coil voltage and supports panel mounting.

Feature Summary

• Supports frequency range up to 40 GHz with SMA 2.9 interface
• Integrated TTL driver compatibility with built-in suppression diodes
• Normally open switching configuration for signal routing
• High reliability design suitable for demanding RF environments

Applications

• Test and measurement instrumentation
• Telecommunications base stations
• Aerospace and defense radar systems
• Satellite communication ground equipment

Procurement Notes

Verify current availability status directly with the manufacturer or authorized distributors, as supply chain conditions may vary. Confirm that the specific ordering suffix matches the required connector type and control logic options. Ensure compliance with relevant environmental regulations such as RoHS standards before finalizing procurement orders for production integration.

Selection Notes

Select this component when high-frequency performance up to 40 GHz is required in a compact form factor. The integrated TTL driver simplifies control circuitry design compared to switches requiring external drivers. Consider the normally open state for fail-safe applications where power loss results in an open circuit. Evaluate thermal management requirements based on the specified coil power dissipation during continuous operation.
