What are SMB RF Connectors?

SMB RF Connectors are miniature push-in RF coaxial Connectors manufactured in accordance with the MIL-C-39012 standard. The characteristic impedances are 50 ohms and 75 ohms in the frequency range 0-4 ghz, the utility model has the advantages of small volume, light weight, convenient use, fast inserting and dialing, superior electric performance, etc. .

What is SMA connector?

SMA RF Connectors are miniature push-in RF coaxial Connectors based on MIL-C-39012 standard. The characteristic impedance is a small RF coaxial connector with thread connection. The characteristic impedance is 50 ohms, frequency Range 0-18GHz, with mechanical and electrical performance, high reliability and other advantages. It is widely used in telecommunication, network, wireless communication, testing and measuring instrument, microwave communication, spaceflight and navigation, weapon system, microwave measuring equipment and so on.

The difference between SMB RF Connectors and SMA RF Connectors.

1. Impedance

Different connectors have different impedance, generally only 75 ohms and 50 ohms. It can be selected according to its own required impedance;

2. Different shapes

Look at the shape of their own needs, and manufacturers request, is customizable, even if the SMB RF Connectors may also have a very different shape! But the inner diameter is constant;

3. Different caliber

Interface is not the same, there are differences in connection, the same model can be used with each other, the need for different types of adapter can be used with.
