Overview
The Radiall R574403835 is a high-performance SP8T coaxial switch from the Ramses series, designed for demanding RF applications up to 18 GHz. It features a latching mechanism powered by 28 VDC and utilizes a D-sub connector for control interface integration. The unit provides terminated ports with SMA connectors, ensuring stable impedance matching at 50 Ohms. Key electrical specifications include a maximum VSWR of 1.6, insertion loss of 0.6 dB, and isolation of 60 dB. It operates within a temperature range of -40°C to +85°C.
Feature Summary
- SP8T configuration with terminated output ports
- High-frequency operation up to 18 GHz
- Latching mechanism with 28 VDC coil voltage
- D-sub connector for control signal interface
Applications
- Test and measurement equipment requiring multi-port signal routing
- Telecommunications infrastructure switching systems
- Aerospace and defense radar signal distribution networks
Procurement Notes
Verify current lifecycle status directly with Radiall or authorized distributors, as availability may be limited. Confirm that the D-sub connector type and SMA port termination match your system requirements. Ensure the 28 VDC latching voltage aligns with your control circuitry capabilities before procurement.
Selection Notes
Select this component when an eight-channel switched path is required at frequencies approaching 18 GHz. The terminated design simplifies system integration by eliminating open-port reflections. Verify that the physical footprint of the D-sub connector fits within your enclosure constraints and that the 28 VDC power supply is available in the design.
Part Context
This part belongs to the Ramses family of coaxial switches, known for robust performance in harsh environments. The R574403835 specifically denotes the SP8T topology with SMA connectors and D-sub control interfaces. It serves as a critical interconnect solution for complex RF signal management tasks where high isolation and low loss are paramount.
Replacement Considerations
Check for discontinued status alternatives within the Ramses series. Verify if other SP8T variants with different connector types (e.g., N-type) or lower frequency ratings meet the application needs. Cross-reference pinouts for any substitute models to ensure compatibility with existing D-sub control wiring.
