R570123100LP

RF Switches Overview

The R570123100LP is a general-purpose Single Pole Double Throw (SPDT) RF switch integrated circuit manufactured by Radiall USA, Inc. Designed for applications requiring low passive intermodulation (PIM), this component operates with a characteristic impedance of 50 Ohms and supports frequencies up to 12.4 GHz. It features a failsafe mechanism and utilizes TTL diode pin terminals for control, powered by a 28Vdc supply.

RF Switches Feature Summary

• Single Pole Double Throw (SPDT) configuration for signal routing
• Low Passive Intermodulation (PIM) design for high-fidelity transmission
• Failsafe operational capability ensuring reliable state retention
• TTL diode pin terminal interface for digital control

RF Switches Applications

• RF signal routing in communication systems
• Test and measurement equipment requiring low PIM
• Avionics data transmission interfaces
• Radar and sensor signal processing chains

RF Switches Procurement Notes

Verify the specific ordering suffix and package type against the official Radiall datasheet to ensure compatibility with existing PCB footprints. Confirm that the 28Vdc TTL control requirements align with the system's power management architecture before procurement.

RF Switches Selection Notes

Select this component when low PIM performance is critical for signal integrity at frequencies approaching 12.4 GHz. Ensure the design accommodates the 28Vdc supply voltage and validates the failsafe behavior against system safety requirements. Compare against standard SPDT switches if higher frequency or different control logic is needed.

RF Switches Part Context

This part belongs to Radiall's Ramses series of coaxial switches, which are engineered for demanding environments. The series emphasizes reliability and performance in aerospace and military applications, often featuring ruggedized construction suitable for extreme conditions.

RF Switches Replacement Considerations

Consult the manufacturer's cross-reference guide for direct substitutes. Verify that any alternative maintains the 50 Ohm impedance, SPDT topology, and 12.4 GHz frequency limit without compromising PIM specifications.
