R573452420

Overview

The R573452420 is a general-purpose RF switch IC from the RAMSES series, manufactured by Radiall USA, Inc. It features an SP4T (Single-Pole, Four-Throw) topology with SMA connectors and operates up to 18 GHz. The device utilizes latching technology for state retention and includes self-cut-off indicators. Designed for robust performance in demanding environments, it supports TTL diodes and pins terminals for control interface integration.

Feature Summary

• SP4T single-pole four-throw switching topology
• Operational frequency range up to 18 GHz
• Latching mechanism with self-cut-off indicators
• SMA connector interface

Applications

• RF signal routing in communication systems
• Test and measurement equipment signal paths
• Aerospace and defense radar subsystems
• Wireless infrastructure base station modules

Procurement Notes

Verify component authenticity through authorized Radiall distributors or direct manufacturer channels. Confirm datasheet revisions match specific lot codes. Ensure environmental compliance documentation aligns with project requirements. Validate electrical specifications against current application loads before procurement finalization.

Selection Notes

Select this component when high-frequency signal switching up to 18 GHz is required. The SP4T configuration suits applications needing one input routed to four distinct outputs. Latching functionality reduces continuous power consumption compared to non-latching alternatives. Verify mechanical compatibility with SMA mating interfaces and control voltage levels.

Part Context

Part of the RAMSES series, designed for reliable RF switching in compact form factors. The series emphasizes durability and consistent performance across varying environmental conditions. Integration into larger systems requires attention to thermal management and signal integrity considerations inherent to high-frequency microwave components.

Replacement Considerations

R574402410 is a confirmed substitute within the same RAMSES series offering identical SP4T topology and 18 GHz operational limits.
