Mini-UHF Terminators

At Amphenol RF, our Mini-UHF terminators provide a streamlined solution for properly terminating unused ports or signal lines in systems requiring the miniature 3/8-24 thread interface. Mini-UHF connectors are designed to deliver excellent RF performance—up to ~2.5 GHz—for cost- and size-sensitive applications.

Whether deployed in telecommunications, automotive, test equipment or portable RF modules, these Mini-UHF terminations help preserve signal integrity, reduce reflections and simplify inventory with a familiar yet space-efficient footprint.

Features and Benefits

• Standard 50 Ω impedance termination compatible with Mini-UHF series connectors—ensures system matching and minimal signal reflection.
• Threaded 3/8-24 coupling provides reliable mechanical connection in modular or compact system layouts.
• Miniaturised form-factor meets space- and weight-sensitive design requirements, helping reduce board-or-panel real estate.
• Broadband performance to ~2.5 GHz supports a wide range of RF, wireless and general-purpose coaxial applications.
• Trusted platform backed by Amphenol RF’s documentation and global supply infrastructure—facilitating engineering selection and system integration.

Key Technical Details

• Impedance: 50 Ω.
• Frequency range: Up to ~2.5 GHz typical for the Mini-UHF connector family; actual termination performance depends on cable type and assembly conditions.
• Mating cycles: The threaded interface supports multiple connect/disconnect operations; one datasheet cites 500 mating cycles for a Mini-UHF connector.
• Temperature range: One Mini-UHF datasheet shows –65 °C to +165 °C. Note: actual terminator device rating may vary based on material and termination style.
• Special features: Miniature 3/8-24 thread, small footprint, standard impedance matching termination. Note: These terminations are not described as hermetically sealed or IP67 rated in the standard product documentation.

Applications

• RF modules in telecommunications or wireless infrastructure where Mini-UHF connectors are used and spare ports must be terminated.
• Automotive or portable wireless devices where size and weight are constrained and high-performance termination is needed at ~2.5 GHz.
• Test and measurement equipment, instrumentation or calibration rigs employing Mini-UHF interfaces where unused ports require reliable termination to preserve measurement accuracy.
• Cable-assembly endings, panel-mount blocks or system enclosure modules in RF or broadband systems where compact termination is beneficial.
