Abstract
The article shows a methodological approach to assessing and selecting a manufacturer of microwave components from China for possible use in radioelectronic equipment. The approach is based on a generalization of practical work experience and reflects those main and characteristic points that a development engineer usually takes into account. Keywords: microwave components, business model, Chinese manufacturer, organizational and economic criteria, technical criteria, fabless company.
