Intermediate Frequency Circuit Design for a 60GHz LFMCW Radar

摘要：

This paper describes an intermediate frequency (IF) circuit design in a 60GHz linear frequency-modulated continuous-wave (LFMCW) radar system. The IF circuit includes a preamplifier stage, an auto-gain amplifier stage and an analog-to-digital (ADC) stage. Totally the IF circuit has a gain of more than 120dB, which helps the system to have the ability of detecting target with distance of 150m. The details of the IF circuit design are presented and the experimental results of the whole radar prototyping system are given.
