Research of the methodology of evaluation of the linear range of components of microwave photonic paths using microwave photonic vector analyzers

The paper describes the features of determining the linear dynamic characteristics of an optoelectronic component base as part of radiophoton vector analyzers. Using the example of computer models it is shown that the basic techniques used for radio engineering paths cannot be fully adequate due to the serious difference in the dynamic characteristics of the modulating cascade and the photodetector. In this regard, approaches to the formation of special structural probing radiation are proposed and investigated to minimize this effect.
