1. BNC Characteristic impedance
The characteristic impedance of BNC radio frequency connectors is 50Ω and 75Ω. Many series of connectors have both 50Ω and 75Ω specifications. Generally speaking, 50Ω connectors are mostly used for high-frequency and high-performance products; 75Ω connectors are mostly used for products with lower frequencies, and the frequency is mostly below 4GHz, especially for consumer electronic video. Users should choose a connector that matches their impedance according to their own products. If the user uses a 75Ω RG 59 Cable, he should choose a 75Ω connector.

2. BNC Frequency
Each type of radio frequency connector has a frequency range, and the user should understand the working frequency of his product to choose the connector. Choosing a connector lower than the required operating frequency will affect the electrical performance of the whole machine; or choosing expensive, high-precision and high-frequency connectors will cause waste. It should be noted that the frequency of use of connectors designed by different companies is quite different, and the frequency of use of inferior products is far from reaching the industry standard. When selecting the connector, the user should confirm the electrical performance description of the product.

3. BNC VSWR
VSWR is one of the most important performance indicators of RF connectors. It is a measure of the amount of signal returned from the connector. It is a vector unit including amplitude and phase components. The VSWR of the same type of connector is different at different frequency of use. Generally speaking, the higher the frequency of use, the higher the VSWR. If the user wants to know the VWSR of the connector at a certain frequency, he can ask the manufacturer.

The connectors are the mating elements which lines connected with appropriate ,Electronica mechanical components that enable the circuit to be turned on and off.They are called as plug-ins, plugs and sockets,With the difference among object, frequency, power, application environment.There are different types of connectors.for example,In aviation, There are aviation plug, aviation socket and so on,In life,waterproof connectors and cable connectors are used,In society,Connectors are widely used in military systems such as aviation, spaceflight and national defense.

一,The choice of connector series is based on the application environment of the required product.

1. wireless base station.

2. Transmission equipment, switching equipment.

3. Backplane, set-top box, network card.

The choice of connector series is based on product performance and mechanical requirements.Such as impedance matching,VSWR,maximum frequency,Transmission power matching etc,A typical application environment can lead you to connect the parts of the product catalog.

1. wireless base station

Wireless base stations need to emit high power radio frequency signals, high-speed digital signals, and similar signals.

Input/output port of equipment housing generally use N type and 7/16 type connectors.embedded rf modules require a blind matching series.Like BMA series,DIN series import module and panel connector,input/output modules use MCX,Surface mount series, panel and cable connector,Finally,The semi – rigid cable assembly and soft cable assembly are used to complete the signal connection of all parts of the equipment.

2.Transmission equipment and exchange equipment

In today’s large capacity transmission equipment market,Voice transmission, data transmission, image transmission,It includes connectors, cable assemblies, various consumables, from local end to user, from basic equipment to set-top boxes,From 50Ω to 75Ω,All use small rf coaxial connectors,Like BNC,TNC series, to subminiature MCX.SMA.SMB.SMC and the miniaturized versions of them SSMA,SSMB,SSMC,The mini like MMCX,It provides extremely high installation density,In the standard interface among DIN IEC, High-speed signal transmission requires high – performance GHz band BNC connectors.Wiring equipment is used between transmission equipment and switching equipment,The DDF connector should be used.

DDF(Digital Distribution Frames):With the development of communication technology,High volume SDH,ATM and other devices are widely used,This requires a corresponding development of the RF coaxial connector of its basic components.It should be smaller in size, wider in frequency band, better in performance and more reliable in connection,Dison relies on his own independent development of radio frequency/microwave connector transition compensation CAD system,The connectors of L9(Siemens), C3(AT &T), C5(NEC), C6(Fujitsu) and ERI(Ericsson) have been optimized. Make it more reliable and better meet the requirement of high-speed communication in the future.

Connector is used in three series wiring systems of C4, SMZ and CC4 developed by Dosin in accordance with international standards,Innovative modular design, smaller size, high frequency, excellent electrical performance.

3. Backplane, network card and set-top box

The market of coaxial connector has developed rapidly in recent years,BNC connectors account for a large number of applications in coaxial exit ethernet that provide high-speed access.

BNC series connectors are widely used in the lower layer of communication link,BNC series has been widely used because of its unique lock mode of bayonet and its feature of convenient plug.
