Serie 1.85mm


1.85mm Type
was developed in 1986 at Hewlett-Packard by Julius Botka and Paul Watson. There was no need for compatibility with the SMA, and any corresponding requirements could be left without consideration. The 1.85mm type is available in all three quality standards for production, instrumentation, and metrology.
The 1.85mm high frequency connector is a type of coaxial connector that is used in a variety of applications, including RF, microwave, and high- frequency applications. It is a small, compact, and lightweight connector that is designed to provide high-performance connections in tight spaces.

It is designed to be used with a semi-rigid, low-loss coaxial cable, which helps to reduce insertion losses and provides good shielding. It has a snap-on locking mechanism, which helps to ensure a secure connection and provides superior shielding performance. The 1.85mm connector is available in a wide range of configurations and can be used to connect a variety of devices, such as antennas, amplifiers, and other RF components. It is also widely used in telecommunications equipment and mobile networks.
The 1.85mm connector helps to reduce insertion losses by providing a secure connection between two components. The 1.85mm connector features a metal shell, which provides good shielding against electromagnetic interference. The metal shell also helps to ensure a secure connection between the two components, reducing the possibility of accidental disconnection. Additionally, the 1.85mm connector has a low return loss, meaning that it can provide a more consistent signal. This helps to reduce the amount of signal loss that can occur when transmitting between the two components. The most commonly available coaxial cables with a 1.85mm connector are RG-174 and RG-316.


  • Increased durability: The 1.85mm connector offers greater durability than other types of connectors due to its thicker diameter, which is less prone to bending and warping. This means it can withstand greater force and pressure than thinner connectors, making it more reliable and less likely to fail.
  • Improved signal integrity: The 1.85mm connector provides better signal integrity due to its larger diameter. This means that it can carry more data and provide a better signal quality than thinner connectors.
  • Lower cost: The thicker diameter of the 1.85mm connector means that it is cheaper to produce than other types of connectors. This makes it a cost-effective choice for many applications.
  • Easier installation: The 1.85mm connector is easier to install than other types of connectors due to its larger size. This makes it ideal for applications where space is limited or where installation needs to be done quickly.
