R570443100

Overview

The R570443100 is a single-pole double-throw (SPDT) coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It operates with SMA connectors and supports frequencies up to 18 GHz. The device utilizes a latching mechanism driven by 28 Vdc TTL signals. Key electrical specifications include an insertion loss of 0.35 dB maximum, isolation of 60 dB minimum, and a voltage standing wave ratio (VSWR) of 1.4:1. It features solder pin terminals for PCB mounting and maintains a 50 Ohm impedance.

Feature Summary

• SPDT configuration with SMA interface
• Latching operation via 28 Vdc TTL control
• High isolation and low insertion loss performance
• Solder pin terminal mounting style

Applications

• RF signal routing in communication systems
• Test and measurement equipment setups
• Aerospace and defense radar applications
• Satellite ground station infrastructure

Procurement Notes

Verify component authenticity through authorized Radiall distributors or direct manufacturer channels. Confirm datasheet revisions and lead times prior to order placement. Ensure storage conditions comply with moisture sensitivity levels if applicable. Cross-reference part numbers carefully to avoid confusion with similar Ramses series variants. Request certification documents for quality assurance compliance.

Selection Notes

Select this model when SPDT switching at 18 GHz is required with latching functionality. Consider the 28 Vdc TTL drive requirement for control circuit design. Evaluate thermal management needs within the -40°C to +85°C operating range. Compare insertion loss and isolation specs against system budget requirements. Verify SMA connector compatibility with existing RF chain components.

Part Context

This component belongs to the Ramses family of high-performance coaxial switches designed for demanding RF environments. The series offers various configurations including SPDT and SP4T options with different frequency ranges. The R570443100 specifically targets applications requiring reliable signal path switching with minimal signal degradation at microwave frequencies.

Replacement Considerations

Consult official Radiall substitution guides for compatible alternatives. Verify mechanical footprint and pinout compatibility before substituting. Check electrical parameter equivalence for critical RF performance metrics.
