SMP sockets: why they are needed and how to choose them

Quality connection is the foundation of successful operation of any radio frequency equipment. For this, SMP (Sub-Miniature Push-on) sockets are ideal – compact and convenient connectors that have become widely used in radio electronics around the world.

Selteq https://selteq.com.ua/smp/ offers a wide selection of SMP sockets at optimal prices and with a quality guarantee - direct import. Delivery via "Nova Poshta" can also be ordered, or you can pick it up from the warehouse yourself.

The main function of the socket is to establish a reliable electrical connection between the central conductor and the shield of coaxial cables. This ensures the transmission of RF signals without distortion.

Each SMP socket features a convenient push-on mechanism, which greatly simplifies cable connections. This is especially useful when contacts need to be frequently reconnected.

Another advantage of SMP is its compact size. Therefore, if you are working with small electronic devices, these sockets are an excellent choice for working in tight spaces.

SMP connectors are designed to operate over a wide frequency range, typically up to 40 GHz and beyond. Therefore, they are suitable for a wide range of RF applications, including:

It is also worth noting that the structure of SMP connectors is 100% impact-resistant, so even under significant mechanical loads, the contact will remain stable.

When choosing a socket, first consider the specifics of its future application. You should determine whether you need a socket for mounting on a printed circuit board (surface mount or through-hole), for connecting a cable, or for installation on a device panel.

Next, pay attention to the "gender" of the connector, male or female, depending on what type of connector it will be connecting to. It is important to consider the impedance (electrical resistance) of your system, which is often 50 Ohms, otherwise the signal will be "reflected."

Make sure that the maximum operating frequency of the socket matches the frequency range in which your system will operate. No less important are the material of the housing and the coating of the contacts, which affect the durability and corrosion resistance of the connection. Additionally, consider the mechanical characteristics, namely the number of connection/disconnection cycles and the necessary force for this.
