Coaxial Connectors (RF) - Adapters

A coaxial connector is an electrical connector used in many RF applications. Coaxial connectors are used to connect two devices with coaxial cables. The physical and electrical characteristics of a coaxial connector depend on the type of material used and the design of the connector assembly. The most common types of coaxial connectors are: RG-6, RG-11, BNC, SMA, SMB, TNC, and F.

Overview of Coaxial Connectors (RF)

Coaxial connectors are the most widely used type of interconnect for RF applications due to their ease of use, cost effectiveness, and durability. They are made of a dielectric jacket with conductors (shield and central conductor) surrounding a central conductor. Coaxial connectors are used in a variety of applications like cable television, satellite television, radio-frequency (RF) transmission, telephone systems, computer networks, and other electronic systems. Coaxial connectors are also used in automotive, medical, and industrial systems.

72978 Application Field and Working Principle

The 72978 connector is a type of RF coaxial connector commonly used in a broad range of applications, such as aircraft avionics, cellular telephone systems, satellite earth stations, and global navigation systems. It is designed to be highly reliable, durable, and easy to install and use.The 72978 connector has a bayonet coupling method, a snap-ock design, and an 87-mm long threaded sleeve. The typical working voltage of the 72978 is 250VAC/50VAC, and its insertion loss is less than 0.6 dB at 810 MHz. The 72978 connector is rated for use with either 50 Ohm or 75 Ohm coaxial cables. The outer contact of the 72978 connector is normally soldered directly to the outer contact of the coaxial cable. The inner contact is then soldered to the center conductor of the cable.

Advantages and Disadvantages of Coaxial Connectors (RF)

Coaxial connectors have several advantages over other types of connectors. They are easy to install and use, relatively inexpensive, and provide excellent RF shielding. The connectors are also very durable and are capable of handling high power levels up to 10 Kw. However, coaxial connectors do have some disadvantages. The connectors can be bulky and heavy, which can make them difficult to use in tight spaces. The connectors are also sensitive to temperature changes, so they must be carefully handled when in use. Finally, the connectors can corrode over time, so they must be checked regularly to ensure proper operation.
