In a VNA Trilateral Stacker, "VNA" stands for Vector Network Analyzer.

A Vector Network Analyzer is an important test instrument that measures and analyzes the S-parameters (scattering parameters) of a Device Under Test (DUT), thereby evaluating the performance of RF and microwave components. Its core advantage lies in its ability to simultaneously measure the amplitude and phase information of signals, which is crucial for high-precision, high-frequency applications.

VNAs are key tools for verifying designs in RF and high-frequency applications, enabling rapid and accurate verification of RF component performance.

How does a "three-sided stack" enhance the capabilities of a VNA?

While VNAs themselves are powerful, traditional standalone VNAs are often limited by the number of ports when handling complex applications requiring simultaneous measurements of multiple ports (such as three or more ports). The VNA Trilateral Stackerer is a solution developed to address this limitation.

A "three-sided stack" typically refers to a modular, stackable VNA system architecture that allows multiple VNA mainframes or key modules to be combined to easily expand the number of channels. For example, stacked devices enable simultaneous measurement capabilities for 4, 6, or even more ports.

Application Advantages:

• High-Performance Measurement: Combining the accuracy of VNAs, the VNA Trilateral Stackerer can handle differential signal testing and the testing needs of high-port-count components (such as complex filters and antenna arrays).
  
  
• Optimized Space and Cost: The modular and stacked design effectively saves production line testing space, while enabling low-cost multi-channel calibration measurements through resource sharing.
  
  
• Wide Applications: Whether it's 5G FR2 component testing, millimeter-wave applications, or complex cable assemblies and PCB impedance testing, this system provides the required number of channels and measurement accuracy.
  

The VNA Trilateral Stackerer is an important extension of vector network analyzer technology to meet modern high-port testing needs. Through its innovative stacking design, it breaks through the physical limitations of traditional instruments, providing RF engineers and manufacturers with a flexible, powerful, and cost-effective solution. With the rapid development of high-frequency communication and radar technologies, the role of such systems in ensuring product quality and accelerating time-to-market will become increasingly prominent.
