RF coaxial connector terminators are passive components designed to match the characteristic impedance of coaxial cables and systems, preventing signal reflections that cause interference and power loss. They are critical in maintaining signal integrity in high-frequency applications. These terminators absorb transmitted energy, ensuring optimal performance in RF circuits, test systems, and communication networks.
| Type | Functional Features | Application Examples |
|---|---|---|
| N-Type Terminator | 50 impedance, threaded coupling, weatherproof design | Cellular base stations, microwave systems |
| BNC Terminator | Quick-connect bayonet style, 50/75 options | Test equipment, video systems |
| SMA Terminator | Subminiature threaded design, 0-18 GHz frequency range | Wireless communication modules, aerospace systems |
| TNC Terminator | Threaded BNC variant, vibration-resistant | Military radios, mobile networks |
| F-Type Terminator | 75 screw-on design for CATV systems | Cable TV modems, satellite receivers |
Typical terminators consist of: - Outer conductor (copper/aluminum) for shielding - Dielectric material (PTFE/ceramic) maintaining impedance - Center conductor termination resistor (precision chip) - Threaded/snap-fit coupling mechanism - Corrosion-resistant plating (nickel/gold)
| Parameter | Description | Importance |
|---|---|---|
| Impedance ( ) | Standard 50 /75 matching | Ensures minimal signal reflection |
| Frequency Range | DC-18GHz for SMA, DC-11GHz for N-Type | Defines operational bandwidth |
| VSWR | 0.1-2.0:1 ratio | Measures impedance matching quality |
| Power Handling | 10W-500W average power | Determines thermal stability |
| Environmental Rating | -55 C to +165 C operating temp, IP67 | Guarantees reliability in harsh conditions |
| Manufacturer | Representative Product | Key Features |
|---|---|---|
| Amphenol | 901-5066 SMA Terminator | 18GHz, 50 , VSWR 1.1:1 |
| TE Connectivity | N-Term-50-12 N-Type | IP68 rated, 500W power handling |
| Keysight Technologies | 8120-0033 BNC Terminator | 50 precision load for lab testing |
| Rosenberger | 806 343S TNC Terminator | Corrosion-proof, -40 C to +125 C |
Key considerations: - Impedance match with system (50 vs 75 ) - Frequency requirements (check cutoff points) - Environmental conditions (temperature, moisture) - Connection type (threaded vs quick-connect) - Power dissipation needs (high-power applications require larger terminators) - Industry standards (MIL-STD, IEC, EIA)
Current developments include: - Miniaturization for 5G mmWave applications (2.4mm, 1.85mm connectors) - Enhanced thermal management for high-power 5G arrays - Standardization of 75 terminators for automotive radar (76-81GHz) - Adoption of RoHS-compliant materials (lead-free plating) - Integration with smart monitoring systems for network health diagnostics - Development of reusable terminators for lab environments
