Introduction to Coaxial Connectors (RF)

Coaxial connectors (also known as RF connectors) are one of the most popular types of electrical connection used in radio frequency (RF) applications. The name “coaxial” comes from the nature of the signal transfer along the inside of the connector in a circular, or helical, fashion similar to a coaxial cable. These connectors are available in a range of sizes and shapes, with various types capable of operating within different frequency ranges, power levels, and impedance match. The generic term “coaxial connector” is usually used to refer to standard series such as the N, BNC, TNC, SMA, and SMB etc.

Application and Working Principle of 125-0701-801

The 125-0701-801 coaxial connector is a straight-taper type RF connector with a 7/16 DIN Female Bayonet Coupling feature. It is designed to provide a secure electrical connection for antenna applications that operate within the frequency range of 2-11GHz. This connector has an insertion loss of only 0.2dB and a VSWR of less than 1.2:1, meaning it can be used for a wide variety of linear applications.

The working principle behind the 125-0701-801 connectors is based on the design of the inner conductor and the outer shell, which create an electromagnetic interference shield. The conductors are held together by a dielectric material, such as polyethylene, which helps prevent signal leaks and distortion. The internal connections, which include two radiating absorbers and an E-plane absorber, also help to maintain the desired impedance match.

The 125-0701-801 has an operating temperature of -65 degrees Celsius. It can be used in a variety of indoor and outdoor applications, such as base station antenna systems, long-distance radio links, microwave antennas, and multi-way radio propagation systems. It is also widely used in broadcast production, wireless data, and telecommunication systems.

Conclusion

The 125-0701-801 coaxial connectors are a reliable and secure connection for RF applications and are designed to provide a low-loss electrical connection at a variety of levels and frequencies. They have an impressive operating temperature of -65 degrees Celsius and a small size for use in even the tightest spaces. With its E-plane absorber, dielectric material, and two radiating absorbers, the 125-0701-801 can help provide dependable transmission for many different indoor and outdoor applications.
