R570612030

Overview

The Radiall R570612030 is a coaxial switch belonging to the Ramses series, designed for high-frequency signal routing applications. It features an SPDT (Single Pole Double Throw) configuration with TNC connectors and operates up to a maximum frequency of 12.4 GHz. The device utilizes a failsafe mechanism activated by a 12Vdc coil voltage, ensuring reliable state retention during power loss. Electrical performance includes a VSWR of 1.25:1 and insertion loss of 0.25 dB, with an isolation rating of 75 dB. The unit supports diode pin terminals for soldering and offers a mechanical lifespan of 2,500,000 cycles within an operating temperature range of -40°C to +85°C.

Procurement Notes

Verify component authenticity through authorized Radiall distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required connector type and terminal configuration. Request official datasheets and compliance documentation, such as RoHS status, prior to finalizing procurement orders to ensure alignment with project specifications and regulatory requirements.

Selection Notes

Select this model when a fail-safe SPDT switching solution is required for frequencies up to 12.4 GHz. Ensure the system provides a stable 12Vdc supply for the coil actuation. Verify that the TNC connector style and diode pin terminal format are compatible with the PCB layout and cable assembly interfaces. Consider the operating temperature range and cycle life requirements against the application's environmental and duty cycle constraints.

Part Context

This component is part of the Ramses family of coaxial switches from Radiall, known for high-performance RF switching in demanding environments. The Ramses series encompasses various configurations including SMA, N, and TNC interfaces with different frequency ratings and latching or failsafe mechanisms. This specific model targets applications needing reliable TNC-based switching at microwave frequencies.

Replacement Considerations

For equivalent functionality, consider the R570412030 (SMA interface, 18 GHz) or R570012030 (N-type interface, 3 GHz). These alternatives share the same Ramses series architecture, failsafe 12Vdc operation, and similar electrical characteristics but differ in connector type and maximum frequency rating.
