What are the names of these two types of coaxial cable connectors?

1、 N-type connector:
N-type connector is a common coaxial cable connector widely used in communication systems, wireless local area networks, RF equipment, and other fields. The name of the N-type connector comes from the initials of the surnames of its inventors Paul Neill and Carl Concelman. The characteristics of this type of connector mainly include:
Wide frequency range: N-type connectors are suitable for a wide frequency range, usually covering the frequency range from DC to 11GHz. This makes it highly adaptable in different application scenarios.
Large size design: The N-type connector is relatively large, making it easier to handle high-power transmission in design. This makes it perform well in situations that require high power transmission.
Strong durability: The N-type connector has a relatively simple structure and high durability, which can maintain stable connections in harsh environments.
Suitable for thick and large cables: Due to the relatively large size of the N-type connector, it is more suitable for thick and large diameter coaxial cables, which is very advantageous in some specific engineering requirements.
2、 SMA type connectors:
The SMA type connector is another common coaxial cable connector, named after SubMiniature version A. Compared with N-type connectors, SMA type connectors exhibit unique advantages in some specific application scenarios, with the following characteristics:
Miniaturization design: SMA connectors are relatively small and suitable for scenarios with limited space and limited connector size. This has made it widely used in some lightweight and portable devices.
Moderate frequency range: SMA type connectors are usually suitable for higher frequency applications, covering the range of DC to 18GHz. This makes it perform well in some applications that require high frequency transmission.
High precision connection: Due to its miniaturization design, SMA connectors are very suitable for applications with high requirements for connection accuracy, such as laboratory testing and precision instruments.
Suitable for small cables: SMA type connectors are suitable for small diameter coaxial cables, which are very important in some lightweight applications and portable devices.
