SMA RF Coaxial Connector---ZOMWAVE

The operating frequency of the SMA connector is 22GHz. It is not a millimeter wave connector, but it has a great influence on the development of millimeter wave connectors, so it is necessary to introduce it first. The matching space of SMA connector is filled with polytetrafluoroethylene medium, and the structure is relatively simple. This kind of connector was not intended to be used for a long time, nor was it considered as a precision connector, so it is just a connector for ordinary systems. Under the circumstances at that time, due to its small size and ability to work at higher frequencies, it quickly gained popularity, and even later had to consider compatibility with it when a newer generation of millimeter wave coaxial connectors were developed. However, due to its congenital deficiencies, it also brought some limitations to the later development of small coaxial connectors.

The main problem of SMA  connector is that the accuracy is not high and it is not suitable for the needs of test equipment; secondly, the outer conductor has a thinner wall, and the inner conductor socket has a two-slot structure, which is very easy to be worn and damaged during use; and secondly The operating frequency is not high and cannot meet the needs of systems with operating frequency bands above 40 GHz. Due to these shortcomings of SMA connector, some manufacturers have developed a batch of connectors compatible with SMA connector. The main models are 3.5mm, WSMA, and later developed 2.92mm, MPC3, KMC and WMP4. These connectors overcome the limitations of SMA connector, and are different in structure from SMA connector. As far as the contact area of ​​the outer conductor is concerned, the newly developed connectors are greatly strengthened, which improves the robustness of the connector.
