RF test equipment series: high-precision coaxial cable assemblies

Performance standard

The main performance gap between the product level and the precision coaxial cable assembly is the rg402 mechanical tolerance of the connector and cable, as well as several critical electrical properties. These electrical parameters include insertion loss, voltage standby (VSWR), frequency range, and group times. For example, if the VSWR of the product cable assembly is 1.6: 1, the VSWR of the high-precision test cable is typically less than 1.4: 1.

In addition, in most precision applications, customers wish to have as low insertion loss and as stable groups as much as possible within the coaxial cable assemblies desired frequency rg402 range. In order to meet these requirements, high-precision coaxial cables and connectors typically use more ideal tolerances, materials, and various cable layers, thereby improving performance and is subject to more stringent quality control.

Rigid, semi-flexible and flexible coaxial cable assemblies

RF coaxial rg405 components can be rg402 divided into rigid, semi-flexible and flexible coaxial cable type. The advantage of using rigid or semi-rigid coaxial cables is that without multiple connection / disconnection operations, there is no need to connect / disconnect cycle operations when installing coaxial cable assemblies the movable components and coax cable, more ideal than flexible coaxial cables, rigid and semi-flexible coaxial cables. VSWR and lower insertion loss. However, when the test is rg402 installed, multiple modulated devices (DUT) or multiple processing may be required, and the flexible coaxial cable is used most often. Therefore, in precision equipment such as radar, sensing, research, and automation test, rigid and semi-flexible coaxial cables are more common.

Solar matching coaxial cable

In high-speed digital coaxial cable assemblies signal applications and other parallel communication applications, customers wish to transmit as small as possible between transmission rg402 lines of signals. Therefore, some manufacturers provide a skew matching coaxial cable pair with accurate and designated maximum deflection parameters.

Stable the same coax cable

In the case where multiple subject (DUT) or multiple coaxial cable assemblies processing are required in the test application, the same shaft cable is suitable for use. Such cables maintain their phase characteristics while stretching and bending. Compared to standard high-precision coaxial cables, it allows test settings to keep calibration when moving. This type of cable is especially suitable for manual calibration test settings.

Low PIM coaxial cable

In the case where PIM needs to be considered, a low PIM coaxial cable can be used to ensure additional PIM from the cable assembly minimal. The manufacture of such rg405 components typically requires extraordinary and guaranteed quality, and typically requires the maximum PIM for each component. Typically, this PIM type coaxial cable assembly can be used with high power or precision wireless communication devices or PIM test systems.

Hi-Rel & Armored coax cable

In some applications requiring coaxial cable assemblies rugged durability and extremity, high-precision rg405 requirements are also consistent with high reliability (HI-REL) requirements. Therefore, some Hi-REL coaxial cable assemblies also have high reliability functions, such as armor sheath materials and sealing connectors.
