Design of a Wideband Power Synthesizer for Vector Network Analyzer

For vector network analyzer, the output power of excitation source determines its measurement ability. For this reason, the output power is required to be as large as possible. However, it is difficult to improve the maximum output power in the design of excitation source. This paper introduces a method to improve the output power of excitation source of vector network analyzer with power synthesis technology. The design of power synthesis circuit based on microstrip power divider.
