R570923000

Overview

The R570923000 is a single-pole double-throw (SPDT) coaxial switch manufactured by Radiall USA, Inc. It belongs to the Ramses series and utilizes SMA connectors for interfacing. The component operates at a maximum frequency of 75 GHz with a characteristic impedance of 75 Ohms. It features a latching mechanism and includes self-cut-off indicators. Electrical performance specifications include a voltage standing wave ratio (VSWR) of 1.4:1 and an insertion loss of 0.35 dB. The device provides 60 dB of isolation and supports up to 10 million operational cycles. It functions within a temperature range of -40°C to +85°C and requires a 28 VDC coil voltage.

Feature Summary

• SPDT configuration with SMA interface
• High-frequency operation up to 75 GHz
• Latching mechanism with self-cut-off indicators
• Robust mechanical endurance

Applications

• RF signal routing in high-frequency test equipment
• Telecommunications infrastructure switching
• Aerospace and defense radar systems
• Satellite communication ground stations

Procurement Notes

Verify the specific datasheet version and compliance documentation directly with Radiall USA, Inc. or authorized distributors before procurement. Confirm that the 75 Ohm impedance specification aligns with your system requirements, as this differs from standard 50 Ohm implementations. Ensure compatibility with the required 28 VDC control voltage and latching mechanism type for your application design.

Selection Notes

Select the R570923000 when a 75 Ohm impedance matching network is required for SPDT switching applications operating up to 75 GHz. Consider the latching feature if power conservation during state retention is necessary. Evaluate the 10 million cycle life against the expected operational duty cycle. Verify that the SMA connector style matches the existing board layout and cable assembly interfaces.

Part Context

This component is part of Radiall's Ramses series of coaxial switches, designed for demanding RF and microwave environments. The Ramses line offers various configurations including SPDT and SP4T options with different connector types such as SMA and 2.9mm. The R570923000 specifically addresses the niche requirement for 75 Ohm high-frequency switching, distinguishing it from the more common 50 Ohm variants in the same product family.

Replacement Considerations

Direct substitutes must match the 75 Ohm impedance, SMA interface, and 75 GHz frequency limit. Cross-reference with other Ramses series models like R570F63000 only if impedance differences are acceptable. Verify pinout and control voltage compatibility when considering alternative manufacturers' SPDT switches.
