Overview
The R573402320 is a Ramses series coaxial switch manufactured by Radiall USA, Inc. It features an SP3T (Single Pole Triple Throw) configuration with SMA connectors and operates at frequencies up to 18 GHz. The device utilizes a normally open contact form with positive common logic and requires a 12 VDC coil voltage for actuation. Electrical specifications include a VSWR of 1.5:1, insertion loss of 0.5 dB, and isolation of 60 dB at 50 Ohms impedance. It employs TTL diodes for control and solder pin terminals for mounting.
Feature Summary
- SP3T switching topology with normally open configuration
- SMA connector interface supporting up to 18 GHz operation
- Positive common logic with TTL diode control circuitry
- High isolation performance with low insertion loss
Applications
- RF signal routing in communication systems
- Test and measurement equipment signal paths
- Aerospace and defense radar subsystems
- Cryogenic quantum computing interconnect solutions
Procurement Notes
Verify component status directly with the manufacturer as availability may vary. Confirm specific ordering suffixes match required electrical parameters such as coil voltage and control logic. Ensure compatibility with existing PCB layouts regarding pin terminal dimensions and spacing. Review datasheet for environmental ratings and RoHS compliance details before integration.
Selection Notes
Select this model for applications requiring SP3T switching within the 18 GHz frequency range. Consider the 12 VDC coil voltage requirement for power supply design. Evaluate the SMA connector type against system interface standards. Assess the normally open state behavior against system safety and operational requirements during power loss scenarios.
