Coaxial Connectors (RF)

Coaxial connectors (RF) are an important type of electrical connection used widely in radio frequency systems. One of the most popular types of coaxial connectors is the BJ380, which is used in a wide variety of applications such as television antennas, telecommunications, military radio systems, satellite communications, and more. This article will explore the BJ380 application field and working principle.The BJ380 is a miniature RF coaxial connector designed to provide reliable electrical connection to equipment used in radio frequency systems. It is a 6-mm male-to-female connector with a threaded body and a center contact. It offers a frequency range of DC to 3 GHz and is designed to work with 50 ohm antennas, cable, or equipment. The BJ 380 is a very versatile connector and can be used for a variety of applications, including low power radios and other low power applications.The most common application of the BJ 380 is in the connection of a low power radio to a 50 ohm coaxial cable. It is commonly used in two-way radio systems, such as the citizen band radios often used for short-range communication or in amateur radio systems used for long range communication. The BJ380 is also widely used in television antennas and satellite television systems, allowing for reliable connections to both the antenna and TV receiver. Additionally, it is used in high-power radio systems, such as those used by the military.The BJ380 employs a threaded body design, which makes it very easy to install and provides an excellent seal. It is constructed of metal and is water resistant, making it ideal for outdoor applications. The center contact on the BJ380 is soldered to a ground shield, which greatly improves the signal strength and prevents interference from causing any problems.The working principle of the BJ380 is relatively simple. When the connector is connected, the ground shield is compressed against the mating center contact. This creates a direct electrical path between the contact and the ground shield and ensures optimal signal transmission. Additionally, the threads on the connector provide an additional layer of shielding from external interference.In conclusion, the BJ380 is a versatile and reliable RF connector with a wide range of applications. It can be used in two-way radios, TV antennas, satellite television systems, and high-power radio systems. Its threaded body provides an excellent seal and ensures that the signal is not compromised. Through understanding the BJ380 application field and working principle, its users can ensure a reliable and high-quality connection.
