SMA connector

The SMA (SubMiniature version A) connector is a type of coaxial connector used in electronics, radio electronics and communication systems. This connector is designed to connect and disconnect antennas, cables, and other components in a variety of applications, including wireless communication systems, radio equipment, GPS devices, and other electronic devices.

The main features of the SMA connector include:

Gender: The SMA connector is available in two main genders: male and female. A male connector has an internal thread and an external pin, while a female connector has an external thread and an internal hole. This configuration allows for a reliable connection.

Thread: The SMA connector has a threading mechanism that allows a firm and secure connection between two SMA connectors. This thread is approximately 1/4 inch (6.35 mm) with 36 threads per inch.

Frequency: The SMA connector is used for a wide range of frequencies, making it suitable for radio communication, microwave technology and other applications. Its use spans from a few megahertz (MHz) to gigahertz (GHz).

Applications: SMA connector is commonly used in wireless communication systems, WiFi devices, radio transmitters, receivers, antennas, radio frequency (RF) cables, spectrum analyzer and other components.

Compact design: The SMA connector has a compact design, making it suitable for applications where space is limited.

The SMA connector is widely used in various industries, and its reliable thread mechanism and ability to work in a wide range of frequencies make it popular in the world of radio electronics and communication systems. However, it is important to note that there are different variants of SMA connectors, including RP-SMA (reverse polarity SMA), which have the opposite thread sex, so it is important to choose the right type for a particular application.
