RF Switch – Electro-Mechanical, Absorptive: 50S-1603+XX | JFW Industries

The 50S-1603+XX is a high-performance 1P2T (Single Pole, Double Throw) electro-mechanical RF switch from JFW Industries. Designed for absorptive 50 Ohm systems, it ensures reliable signal routing with internal termination of unused ports. This model is ideal for automated test systems and RF signal distribution requiring failsafe operation.

Advantages:

• Absorptive design with 50 Ohm termination on unused ports
• Failsafe configuration: maintains active path when power is lost
• Wide frequency range: DC to 18 GHz
• SMA connectors for high-frequency integrity
• Available with standard DC or TTL control logic
• Compact and rugged for system integration
