Coaxial Connectors (RF)

In the world of radio frequency (RF) and communications, coaxial is a type of signal cable used in a range of applications with the most notable being television. RF coaxial connectors are used to join sections of coax cable, or to terminate them into a transceiver, an antenna or another type of device. The coaxial connector is usually a male type connector and designed to have a threaded outer walls for easy installation on all types of devices in different radio applications. The most common type of coaxial connections in consumer applications is the 810B-209A.

810B-209A Application Field and Working Principle

The 810B-209A coaxial connector is widely used in telecommunications, mobile radio, antennas, medical electronics, guard systems and other RF related fields. It is also used to connect a signal source to an antenna. 810B-209A coaxial connectors consist of two concentric cylindrical conductors which form the outer and inner conductors. The female connector consists of a metal body which gives mechanical support to the connector, inside the metal body there is a female pin surrounded with dielectric material. The male connector consists of a metal outer shell and an inner male pin. When mated, the dielectric material ensures electrical insulation between the two conductors while the inner conductor makes contact with the inner male pin.
The 810B-209A connector has an impedance of 75 Ohms for optimal signal transmission and reception. This enables signals to be sent down the cable without significant loss of signal strength. 810B-209A connects offer higher data rate than any other type of coaxial connections. This is achieved by having low signal radiation levels, low reflections leading to minimal signal return loss, and a well designed center contact which has lower contact resistance and better electrical performance.
The 810B-209A connector is a popular choice for all types of RF applications, and is used in both commercial and consumer applications. It is suitable for use with flat or round cables and has a single ferrule connection. Due to its wide range of applications, the 810B-209A connector is available from many manufacturers, in a variety of designs, sizes and finishes.
