R573102200

Overview

The R573102200 is a general-purpose RF switch IC manufactured by Radiall USA, Inc. It features a Single Pole Twelve Throw (SP12T) configuration designed for signal routing applications. The component operates with a characteristic impedance of 50 Ohms and supports frequency ranges up to 3 GHz. It utilizes a 12Vdc control voltage and incorporates latching functionality with self-cut-off and auto-reset capabilities. The device includes integrated diodes and indicator pins for status monitoring.

Feature Summary

• SP12T single pole twelve throw switching architecture
• Latching mechanism with self-cut-off and auto-reset functions
• Integrated indicator pins for state visualization
• Built-in diode protection circuitry

Applications

• RF signal distribution networks
• Antenna switching systems
• Test and measurement equipment
• Telecommunications infrastructure

Procurement Notes

Verify the specific datasheet version and lot code markings upon receipt. Confirm that the 12Vdc control requirements align with your system design. Ensure proper handling procedures are followed due to the sensitive nature of RF components. Cross-reference the pinout diagram with your PCB layout before final assembly to guarantee correct electrical connections.

Selection Notes

Select this component when a high-port-count SP12T solution is required within the 3 GHz bandwidth. The 50 Ohm impedance matches standard RF transmission lines. Consider the latching feature for power-efficient operation in battery-constrained environments. Verify that the physical package dimensions fit the available board space constraints.

Part Context

This part belongs to the Ramses series of coaxial switches from Radiall. The series offers various throw configurations and connector types. The R573102200 specifically addresses the need for multi-path signal routing in compact form factors. It complements other models in the family offering different port counts or frequency ranges.

Replacement Considerations

Check for direct substitutes within the same Ramses series offering identical SP12T topology. Verify compatibility with existing control logic levels. Ensure replacement parts maintain the same 50 Ohm impedance and 3 GHz operational limit. Confirm mechanical footprint equivalence if board space is restricted.
