VNA Test Cable --- ZOMWAVE

The use of VNA Test Cable Assembly is often arbitrary and unthinking, but various incorrect use methods may lead to reduced performance and shortened service life of such cables. At lower frequencies, such problems are tolerable due to the larger size of the cables and connectors used. However, because the VNA Test Cable used at mmWave frequencies are smaller in size and generally more fragile, they are also less tolerant of cable abuse.

                                            
The cellular communications industry, which has been operating at 3GHz in the past, is about to adopt the 28-100GHz spectrum. As activity involving mmWave will be more widespread than ever, it is time to revisit the maintenance and treatment of such VNA Test Cable.

                                         
Due to the high degree of integration at the above frequencies, various functions are combined in the same package or circuit board, so the number of VNA Test Cable microwave interconnection devices required may be small. However, even for devices such as small base stations, the connection of VNA Test Cable subsystems still requires flexible, semi-flexible, semi-rigid and other cables. In addition, every device and system operating at these high frequencies must be tested before it can be used, so designers who have not previously experienced the challenges of mmWave measurements will face this challenge right away.

Treatment of test equipment
The test and measurement environment is one of the few areas where careful use and maintenance of VNA Test Cable, connectors, and assemblies is always considered important (though not fully observed in reality). Since measurement uncertainty is a chronic disease of measurement systems, attention to detail is critical. In addition, because precision vector network analyzer test cables (VNA Test Cable) are very expensive, cost is another reason why such cables must be treated with care. Since the interconnects used at mmWave wavelengths are precision machined and fragile, the same applies to all such interconnects.

                                      
For example, the 110GHz VNA Test Cable AAssembly launched by ZOMWAVE, a leading manufacturer of RF cable assemblies in China, is a representative cable assembly used for VNA Test Cable and semiconductor probe testing. These cable assemblies feature 1.0mm male connectors on both ends; insertion loss at 110GHz is less than 5.6dB; typical voltage standing wave ratio (VSWR) is 1.5:1; minimum bend radius for one bend is 1 inch (2.54 cm); connectors are made of gold-plated beryllium copper with passivated stainless steel coupling nut; available in 6" (15cm) and 12" (30cm) lengths.
