This device provides a cost-effective alternative for the bulky and expensive commercial automated vector network analyzers. It can be used whenever coherent reflection/transmission measurements at microwave and millimeter wave frequencies are needed, e.g., network S-parameter measurements, imaging systems, or nondestructive evaluation systems. The device circumvents the heterodyne detection scheme deployed in commercial network analyzers. This makes it compact and low-cost compared to commercial vector network analyzer while maintaining measurement accuracy. Moreover, it can be used directly in high frequency regions in which realizing phased locked sources and highly stable heterodyning process is not feasible either due to cost or technology limitations.
