In the electrical engineering industry, we often encounter the components-connectors, their effects are simple: circulating currents, circuit meet their intended function. Along with the upgrading of product structure, due to the application object, frequency, power, and environmental factors such as different, different types of connectors have been developed are then widely used.
Naming method of RF coaxial connectors type designation type of RF coaxial connectors by the master code and structured code composed of two parts, separated by dashes "-" separated. Master code master code of RF connectors used internationally known symbols, specifically named by the detailed specification of the different structure of specific provisions. In recent years, this kind of connector demand situation has continued to improve. Mainly reflected in the following aspects:
1. miniature miniaturization of machine systems, RF connectors getting smaller and smaller in size, such as the SSMB, MMCX series, volume is very low.
2. high frequency United States HP have launched as early as a few years ago the frequency RF connector to 110GHz. General products used in domestic frequency does not exceed 40GHz. Flexible cable for frequency of use does not exceed 10GHz, semi-rigid cables does not exceed 20GHz.
3. multifunction addition to the bridge, and signal processing functions, such as filtering, phase modulation, mixing, attenuation, detection, clipping, etc.
4. low VSWR, low loss and meet the needs of weapon systems and precision measurement.
5. large capacity, high power main meet the need of development of the information highway.
In addition, the RF connector's two most important part at its electrical and mechanical properties on:
Electrical performance
Actual performance depends on the performance of cable size of contacts, cables, connectors, conductors in contact with, and so on. Coaxial transmission lines is the maximum frequencies must be the weakest component in the maximum frequency of use, because it depends on all the components, not a symbol. For example, an RF connector used is 10GHZ, and the frequency of use of cables connected to it are 5GHZ, the maximum frequency of use of this component is 5GHZ. All a combination of factors determines the frequency of use of the entire transmission line.
Mechanical properties
Processing method of manufacturing various components determines the mechanical and electrical properties of RF connectors. In considering mechanical properties while also taking into account the number and scale of production. Research why a particular performance does not meet the requirements are very important, the occurrence of this kind of analysis can help you avoid errors.
The other hand, the RF connector is smaller, making the more difficult and higher manufacturing costs, accuracy and errors is lower. Commercial application in the future, small, excellent, cheap electronic components will be a growing demand.
