SMP connector is a kind of ultra-small radio frequency connector with application frequency up to 40GHz.     It has several advantages such as small size, light weight, bandwidth, and reliable link.     SMP connectors are often used for board-to-board connections, or occasions with weight requirements and small installation space, and are widely used in new generation communication equipment.     SMP RF connectors have the following 4 notable features:     1. High frequency of use;     2. Fast connection;     3. Strong vibration resistance;     4. Allow a certain amount of mismatch between baseline and democracy;     When purchasing SMP cable connectors, many people will find it difficult to get started because they are not familiar with the product. They can neither confirm the product quality nor choose the appropriate model.     ROHO provides professional technical consulting services and full professional customer service to solve procurement problems.

    The power capacity of RF connector is an important part of the standard to evaluate the quality of rf coaxial connectors. So what do you know about the power capacity of the rf coaxial connector? ROHO will introduce you to this knowledge in detail.     The power capacity of the rf coaxial connector is a complicated problem, which is affected by many factors.     Pin size: the size of the pin is related to the current capacity of the connector and directly affects the power.     VSWR: The reflection wave occupies the channel capacity space, resulting in the transmission power capacity reduction.     Insertion loss: There is a difference between input and output power due to the existence of loss.     Air pressure (altitude): The higher the altitude, the lower the pressure, the smaller the power capacity.     Contact resistance: Contact resistance causes the contact to heat up, making it difficult to transmit high power microwave signals.     Influence of frequency: The change of transmission signal frequency directly leads to the change of loss and VSWR, which affects the transmission power capacity.     For the above reasons are uncertain factors, so the connector is generally not given power capacity value indicators, only in the rf terminator, rf attenuator and other technical indicators of microwave passive components can indicate the index.

    There are many kinds of RF coaxial connectors, including BNC, TNC, F, N, SMA, SMB, MCX, MMCX connector etc. It is a matter of great concern for users to choose a good quality connection that meets their needs in such a variety of connectors.     So how to choose the high quality rf coaxial connector?  ROHO will tell you more details about that.     What kind of rf coaxial connector is high quality, and how to choose such a product? When selecting, we need to take into account the interface type, electrical performance and connection form.     (1).  Interface type     RF connectors are connected not only to provide convenient and fast connection or separation of coaxial cables, but also to provide stable electrical performance and environmental protection devices.     (2). electrical performance     a. Impedance；     b. Withstand voltage；     c. Maximum efficiency     (3).Connection form     Connectors can be used for rf coaxial cable, circuit board, etc. Before using, you must be familiar with the performance of the selected product. When installing the cable connector, you should follow the assembly instructions provided by the supplier.

    In the connector field, the RF coaxial connector is a subdivided category, while under the rf coaxial connector category, there are also related products about the rf coaxial cable connector components. What is an rf coaxial cable connector assembly and how its performance is affected? ROHO will give you some basic knowledge of the rf coaxial cable connector assembly.     It must be clear to those who are engaged in connector manufacturing that the components of the rf coaxial connector cable are composed of two rf coaxial connectors and a certain length of the rf coaxial cable through welding. Therefore, the rf coaxial cable becomes an indispensable part of the rf coaxial cable connector assembly, and its performance is directly related to the performance of the rf coaxial cable connector assembly.     It is concluded that the following six main factors influencing the performance of rf coaxial cable connector components are as follows:     1, The standing wave has bad periodicity.     2, Poor performance due to local deformation;     3, Impedance mismatch (high or low );     4, The movement between the cable foaming layer and the outer conductor;     5, The foaming layer is pasted on the inner conductor and cannot be cleaned;     6, The inner conductor size does not meet the requirements;     The six points above are the mainly influences of the performance of the Rf coaxial cable connector assembly. So the way to enhance the ability of them is that we need to reduce the six failure modes. Meanwhile, the dimension of the inner rf connector must meet the      requirement. When we find the failure modes of Rf coaxial cable assembly, that means we also find the direction of improving the performance of them. It is of great guiding significance to improve the performance of rf coaxial cable in major manufacturers.     In addition, ROHO provide you with several ways to improve cable performance, for your reference as below:     First of all, the selection of internal and external conductor materials should be done well, that is to say, the model and impedance of internal and external conductor and rf connector should be unified. Secondly, in the process of extruding insulation, we should control the foaming uniformity to a high standard, and improve the diameter uniformity of the foaming insulation wire core and the stability of capacitance. The third is to improve the concentricity of the inner and outer conductors, that is, to control the insulation of cables without eccentricity. Finally, the tolerance requirement of inner conductor should be strictly controlled.

There are many types of rf connectors with different shapes and different installation methods. It is difficult for ordinary people to remember all the types and their corresponding shapes and installation methods.  The following figure shows the name, shape and installation of most RF connectors intuitively. Remember to collect it! ROHO  has strong R&D, design, testing and machining production capabilities, and can provide effective interconnection solutions.

    Waterproof connectors are the electron components which work under the water and resist water.Power cords, network cables can be put in their internal. they can provide normal and reliable power supply and the signal transmission. The most important and characteristic role is that they are waterproof and dust proof.     At the moment, the IP waterproofing standard is the main standard of waterproof connector for waterproof performance. We know the waterproof performance by the IPXX, The two number XX behind the IP.first X is from 0 to 6, The supreme grade is 6.The second number is from 0 to 8.  The supreme grade is 8. So the highest waterproofing level of waterproof connectors are IP68.     With the development of technologies. Many stuffs in our life use electricity. But the things with electricity have influence in our safety somehow. So waterproof is important, waterproof connectors can be used into environment with water, have excellent sealing performance and reliable waterproof performance. For example, If some equipment need to be in the water or be fixed in the water. the waterproof connectors have no need to worry about the water especially the water contains many chemical substances come into the connectors which will damage the rf connectors.     Waterproof connectors are the good news for us. They have many applications. Many area need to use the waterproof connectors, Like the industrial environment, lighting decoration controlled, Urban outdoor lighting project, cruise ship, aviation, industrial equipment, cable, sprinklers etc. They all use the waterproof cable connectors. Because the military fields have the strict requires. They use many waterproof connectors, Like submarines and submarine-launched missiles connectors and so on.

    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.     The first，the choice of connector series is based on the application environment of the required product.     1. wireless base station.     2.
