Telegärtner TNC konektor samica na SMA konektor samica koaxiálny adaptér, 50 Ohm, DC-6 GHz, nikel/zlatá J01019A0028

RF technicians and radio amateurs use this TNC female to SMA female adapter to connect 50-ohm coaxial cables with different connector series in test setups, antenna systems, and RF equipment racks. The straight adapter provides a reliable transition between TNC and SMA interfaces without the need for custom cable assemblies.

Key specifications

• Connector 1: TNC female (jack)
• Connector 2: SMA female (jack)
• Impedance: 50 Ohm
• Frequency range: DC to 6 GHz
• VSWR: max 1.25 at 6 GHz
• Body material: brass with nickel plating
• Center contact plating: gold
• Insulator: PTFE
• Operating temperature: -55°C to +155°C

Why choose it

This adapter is built with precision-machined brass and gold-plated center contacts for low insertion loss and stable impedance. The PTFE insulator ensures consistent performance across the full temperature range, making it suitable for both laboratory and field environments.

Ideal use cases

• Connecting TNC-equipped devices to SMA test cables
• Adapting antennas with TNC connectors to SMA instrumentation
• RF prototyping and bench testing
• Maintaining 50-ohm impedance in mixed-connector systems

Good to know

The adapter is a passive inline component with no gender conversion; both sides are female, so male connectors are required on the cables or devices being joined. It is not intended for outdoor use without additional weatherproofing.
