The 7790-2 coaxial connector is one of the most versatile and widely used connectors in the RF industry. It is a standard, full-featured interface that can be used in a wide range of applications and has become a popular choice for connecting RF signal paths.

The 7790-2 connector is based on the multi-pin, 7790-X series of adapters developed by Amphenol. It features a robust machined metal body with an angled, threaded outer shell and a shielded inner shell, making it suitable for use in wide variety of environments. The connector has a 50Ω impedance, which is ideal for most RF applications, and can accommodate up to 30 pin contacts for power, data, and audio signals.

The 7790-2’s primary application field is in the aerospace, industrial, broadcast, and telecommunications industries. It is the connector of choice in many wireless applications, allowing for reliable transmission of both power and data signals. In the broadcast industry, the 7790-2 is widely used to connect antennas to broadcast receivers and transmitters. It is also used in digitized electrical control systems such as automatic train control and home automation systems. The 7790-2 is also suitable for the connection of medical equipment, including medical devices used in MRI and CT scans.

The 7790-2 connector operates through an RF field coupling principle. This involves the creation of an electric field along a coaxial line. A portion of the line is left unshielded, allowing a portion of the electric field to travel through the line. This electric field, in turn, creates a “standing wave” along the coaxial line. The standing wave is inferred through the values of the electrical field on the line. As the standing wave travels along the coaxial line, it develops points of maximum and minimum voltage. This is what allows signals to be sent and received along the line.

The 7790-2 coaxial connector is a reliable, low-cost option for connecting RF signals in a wide variety of applications. It is capable of transmitting both power and data signals, making it an ideal choice for many wireless and broadcast applications. The 7790-2 connector operates through the RF field coupling principle, allowing for reliable data transmission along the coaxial line.
