BJ77

Coaxial Connectors (RF)

BJ77 connectors are a type of coaxial (RF) connectors. They are designed to provide excellent electrical performance in a variety of transmission line systems that require common RF ports. The design of BJ77 connectors consists of a central contact with a grounded outer contact and a threaded bore that allows the mating of the two connectors. This design enables the BJ77 connector to provide a high level of signal integrity and low insertion loss at frequencies up to 2.4GHz.

The distinctive feature of the BJ77 connector is its very rugged shell which makes it especially suitable for applications in challenging environments. It is IP67 rated and resistant to dust and liquid ingress. This makes it ideal for use in outdoor situations where dust and other contaminants could otherwise interfere with electrical performance. As the BJ77 connector is designed to withstand pressure-washing, it is increasingly being used in aerospace and military applications.

In terms of its general working principle, the BJ77 connector operates similarly to other RF connectors. When two connectors are connected, the central contact and the outer contact of one connector mate with the corresponding contacts on the other connector to create an RF path. This RF path has very low insertion loss and very good impedance match. As signals travel along this RF path, they are subject to minimal loss and distortion due to connector components.

In addition to providing a low-loss RF signal path, the BJ77 connectors also feature an ESD protection mechanism. This is achieved by the use of an ESD diode located between the central and outer contacts. The diode prevents the propagation of ESD currents and ensures that no damage occurs to any connected electrical or electronic components. This is particularly advantageous in applications in hostile environments or where there is a risk of electrostatic discharge.

In conclusion, BJ77 connectors are a type of coaxial RF connectors that are designed to provide excellent electrical performance at frequencies up to 2.4GHz. Their unique design features solid construction and IP67 rating, making them suitable for use in challenging environments. They are also equipped with an ESD protection mechanism for added safety. As such, they are gaining popularity in a range of applications in the aerospace and military industries.
