R573123300

Overview

The R573123300 is a SP3T coaxial relay from the Ramses series, manufactured by Radiall USA, Inc. It features N-type connectors and supports frequencies up to 12.4 GHz with a characteristic impedance of 50 Ohms. The device utilizes latching technology with positive common configuration and pins terminals for actuation. Electrical specifications include a maximum coil voltage of 28 VDC, coil current of 0.375 A, and coil power of 10500 mW. Key RF performance metrics comprise a maximum insertion loss of 0.5 dB and minimum isolation of 60 dB. The unit is designed for panel mount installation.

Feature Summary

• SP3T latching coaxial relay architecture
• N-type connector interface supporting up to 12.4 GHz
• Positive common configuration with pin terminals
• High isolation and low insertion loss design

Applications

• Aerospace communication systems
• Defense radar signal routing
• Test and measurement instrumentation
• Telecommunications infrastructure

Procurement Notes

Verify the specific actuator terminal type and driver compatibility (TTL or BCD) against the official datasheet before procurement. Confirm that the latching mechanism aligns with system power management requirements. Ensure panel mounting provisions match the enclosure design. Cross-reference the exact suffix codes to guarantee correct electrical parameters and mechanical dimensions.

Selection Notes

Select this component when high-frequency switching up to 12.4 GHz is required in a compact form factor. The latching feature reduces continuous power consumption compared to non-latching relays. Verify that the N-type interface suits the existing cable assembly. Consider the 28VDC coil requirement for power supply design. Evaluate thermal dissipation needs given the 10500 mW coil power rating.
