Quality connection – the basis of the foundations of successful operation of any RF equipment. SMP (Sub-Miniature Push-on) sockets – compact and convenient connectors, which have become widespread in radio electronics around the world, are ideal for this.
The Selteq https://selteq.com.ua/smp/ company offers a wide selection of SMP sockets at the best prices and with a quality guarantee - its own import. You can also order delivery «by Nova Poshta» or pick it up from the warehouse yourself.
Why is SMP sockets used?
The main function of the socket – is to establish a reliable electrical connection between the central conductor and the screen of coaxial cables. This ensures the transmission of RF signals without distortion.
Each SMP socket has a convenient push-on (push-to-connect) mechanism, which makes connecting cables as easy as possible. This is especially useful when you need to constantly reconnect contacts.
Another advantage of SMP is compact dimensions. Therefore, if you work with small electronic devices, then such sockets are an excellent choice for working in dense space.
SMP connectors are designed to operate over a wide frequency range, typically up to 40 GHz and above. Therefore, they are suitable for the general public of RF spheres, including:
- telecommunications;
- measuring equipment;
- aerospace industry.
It is also worth adding that the structure of SMP connectors is 100% impact resistant, so even under conditions of significant mechanical loads, the contact will remain stable.
How to choose correctly?
When choosing a nest, first of all, take into account the specifics of its future use. You should decide whether you need a socket to install on the PCB (surface or through-mount), to connect the cable or to install on the device panel.
Next, note the «gender» of the connector, male or female, depending on what type of connector it will connect to. It is important to consider the impedance (electrical resistance) of your system, most often it is 50 ohms, because otherwise the signal will be «reflected».
Make sure the maximum operating frequency of the socket corresponds to the frequency range in which your system will operate. Equally important are the body material and the contact coatings, which affect the durability and corrosion resistance of the joint. Also, consider the mechanical characteristics, namely the number of connection/disconnection cycles and the required force to do so.
