On the Possibility of Expanding the Dynamic Range of Broadband High-Frequency Receivers

Abstract

The possibility of expanding the dynamic range of microwave receivers used in passive radar due to circuit specificities of the input linear circuits is considered. Engineering calculations and graphic dependences of the dynamic range as well as an example of constructive implementation and the results of measuring the main parameters are presented. The conclusion is made on the feasibility and expediency of using in microwave receivers with an extended dynamic range of input linear circuits with disableable amplification stages.
