Rozšírenie frekvenčného rozsahu VNA do pásma X

This thesis focuses on measurement of microwave circuits in the X- band. It briefly introduces the reader to the basic distribution of the electromagnetic spectrum and the fundamentals of high-frequency measurement using a microwave vector network analyzer. The main topic of this thesis is to design and implement a microwave circuit that will be able to expand the frequency range of a "low frequency" vector network analyzer HP8752 into the X-band and demonstrate its function by measuring some standard microwave components.
