Characteristics and trend of SMA connector

Author: Date:5/30/2019 1:24:31 AM
   For buyers of RF connectors, SMA connectoris a common type of RF connector. How much do you know about the characteristics and development trend of SMA connectors?


With the continuous development of science and technology and the continuous update of connector production technology, the development of SMA connector has the following six characteristics:

1. With the miniaturization of the whole machine system, the volume of RF connector becomes smaller and smaller, such as MMCX\SSMB series, the volume is very small.

2.SMA connector to high frequency development: as early as a few years ago, the United States HP has introduced frequency up to 110GHZ RF connector. Domestic common products use frequency does not exceed 40GHZ. Use frequency of flexible cable shall not exceed 10GHZ, and semi-rigid cable shall not exceed 20GHZ.

3. Multi-functional development: besides acting as a bridge, it also has the function of processing signals. Such as filtering, phasing, mixing, attenuation, detection and so on.

4. Development towards low standing wave and low loss to meet the needs of weapon systems and precision measurements.

5. Develop towards large capacity and large power, mainly adapt to the development needs of information superhighway.

6. Surface mount technology upgrade, mainly adapt to the development needs of SMT technology, and is conducive to simplifying the wiring structure design of multilayer printed board.
