Презентация основных коаксиальных соединителей
Coaxial connector alludes to the parts used to associate the finishes of two shafts to guarantee that the middle lines of the two shafts are on a similar hub. Basic coaxial connectors available at present incorporate the accompanying:
The BNC connector is a pike type association. It is for the most part utilized for radio recurrence associations underneath 4GHz and is generally utilized in the interconnection of instruments and PCs.
The TNC connector is a screw association, comparative in size to BNC, and its working recurrence can arrive at 11GHz. The screw type is appropriate for vibration condition.
The SMA connector is a strung association, which is the most broadly utilized. There are two sorts of impedances: 50 and 75 ohms. At 50 ohms, the recurrence of the adaptable link is under 12.4Ghz, and the semi-inflexible link is up to 26.5GHz.
The SMB connector is a module self-locking structure with a volume littler than SMA. It is utilized for fast association and is regularly utilized in computerized interchanges. It is a swap for L9. 50 ohms can arrive at 4 GHz, and 75 ohms can arrive at 2 GHz.
SMC connectors are screw associations. Other SMB-like connectors have a more extensive recurrence extend and are frequently utilized in military or high-vibration conditions.
The N-type connector is a strung association and utilizations air as a protecting material. The expense is low and the recurrence can arrive at 11GHz. It is ordinarily utilized in test instruments and is accessible in 50 and 75 ohms.
Also, there are MCX and MMCX connectors, which are little in size and are utilized for thick associations. There is additionally a BMA connector for dazzle mate association of low-power microwave frameworks up to 18 GHz.
Every connector has a military norm and a business standard. The military standard is fabricated by MIL-C-39012. All copper parts, PTFE protection, gold plating inside and outside, the presentation is the most dependable, however the expense is higher. Business standard plans utilize modest materials, for example, metal castings, polypropylene protection, silver plating, and so on., and the unwavering quality is more terrible. Connector materials are metal, beryllium copper and treated steel, and the inside conveyor is commonly gold-plated to guarantee low opposition and erosion obstruction. The military standard requires gold plating on SMA and SMB, and silver plating on N, TNC, and BNC. Since silver is effortlessly oxidized, clients lean toward nickel plating. Protection materials incorporate PTFE, polypropylene and toughened polystyrene, among which PTFE has the best protection execution, yet the expense is higher.
