Overview
The R573412335 is an SP3T coaxial switch from the Ramses series by Radiall USA, Inc. It utilizes SMA connectors and operates up to 18 GHz with a 50 Ohm impedance. The device features normally open logic, positive common configuration, and 12 Vdc coil voltage. Key electrical specifications include a minimum isolation of 60 dB and a maximum insertion loss of 0.5 dB. It supports an operating temperature range of -40°C to 85°C.
Feature Summary
- SP3T switching topology with positive common configuration
- High-frequency operation up to 18 GHz using SMA interface
- Normally open logic control with 12 Vdc actuation
- Low insertion loss and high isolation performance
Applications
- RF signal routing in communication systems
- Test and measurement equipment switching
- Aerospace and defense radar applications
- Electronic warfare subsystems
Procurement Notes
Verify the specific datasheet version and mechanical dimensions prior to integration. Confirm that the 12 Vdc coil voltage requirement aligns with system power supplies. Ensure SMA connector mating compatibility with existing harnesses. Check for any recent design changes or obsolescence notices directly from Radiall USA, Inc. before finalizing procurement plans.
Selection Notes
Select this component when an SP3T switching function is required at frequencies up to 18 GHz. The 12 Vdc drive voltage suits systems with standard low-voltage logic levels. Consider the Ramses series form factor for space-constrained designs requiring high isolation and low insertion loss characteristics in RF paths.
Part Context
This part belongs to the Ramses family of coaxial switches designed for high-performance RF applications. It complements other variants like R573403540 (SP5T) and R573403310 (SP3T) which may differ in throw count or coil voltage. The series provides reliable switching solutions for demanding environments.
Replacement Considerations
R573403310 is a confirmed substitute offering similar SP3T functionality but operates with 28 Vdc coil voltage instead of 12 Vdc. Verify driver circuit compatibility when substituting due to the voltage difference. No other direct substitutes are publicly confirmed.
