Reliable Interconnection for RF Test Systems

Connecting RF instruments, test fixtures and microwave components requires cable assemblies that match the equipment interfaces, operating frequency and routing needs. The SMS-200-48.0-SMS from Smiths Interconnect / Florida RF combines two SMA male straight connectors with Lab-Flex 200 cable, providing a direct connection between compatible SMA female ports.

Its 50 Ω impedance and frequency capability up to 18 GHz support RF and microwave testing, while the 48-inch length provides practical reach between instruments and devices under test.

Key Specifications

• Frequency: Up to 18 GHz
• Impedance: 50 Ω
• Connector 1: SMA male, straight
• Connector 2: SMA male, straight
• Cable: Lab-Flex 200
• Length: 48 in / 1.2192 m

Built for RF Testing and Integration

• Simplify connections: The SMA male-to-male configuration connects compatible equipment directly, reducing the need for intermediate adapters.
• Support practical cable routing: Flexible Lab-Flex 200 cable helps technicians position connections around instruments, fixtures and enclosures.
• Secure mating interfaces: Threaded SMA connectors provide mechanically secure connections when correctly installed.
• Streamline component selection: A defined connector configuration, cable type and length help engineering and procurement teams specify consistent interconnect requirements.

The assembly can connect signal generators, spectrum analyzers, vector network analyzers, antennas, amplifiers, filters and other compatible RF components. Typical applications include:

• RF and microwave design validation
• Antenna measurement and characterization
• Communication module testing
• Laboratory and production testing
• System integration and troubleshooting

For measurement applications, account for cable loss during calibration and maintain appropriate connector torque and bend radius to support repeatable results.
