  • Broadband vector network analyzer with cascaded reflectometers
    Patent number: 11506694
    Abstract: A vector network analyzer configured to analyze a high-frequency signal received is described. The vector network analyzer includes three or more reflectometers, each reflectometer operating at a respective frequency range and having a first terminal and a second terminal. The reflectometers are connected with each other in series such that a combined frequency range of the vector network analyzer is established. A first reflectometer is connected to one of a load or a signal source via its first terminal. A last reflectometer is connected to a test port via its second terminal. At least two reflectometers are interconnected with each other by an interposed frequency selective absorptive filter.
