Two channel balanced RF FMCW FrontEnd for radar applications

This paper presents an analog RF front-end for FMCW radars, designed as a single PCB module, operating in C-band (5–6 GHz) frequencies. The presented RF front-end part is characterized by its relatively small size, small weight and low power consumption. It is possible to use it in different radar applications. In this paper the design process with both laboratory and outdoor measurement results of the manufactured module are presented. For the outdoor measurement the designed RF front-end part was tested as a compact RF module for SAR radars. The results of these tests are also shown in this paper.
