  Abstract

In this paper, we design and implement a broadband LNA(Low Noise Amplifier), a mixer, and oscillators in RF module part for radar detector. For resolving the limitation of the conventional product that the sensitivity is low due to the poor gain flatness, we propose the architecture of RF module part. The proposed RF module part is composed with a broadband 2-stage LNA, a mixer, and three oscillators, and improves the maximum gain and gain flatness for detecting various frequencies. The overall performances of RF module part are above 38 ㏈ conversion gain in whole band and 1 ㏈ gain flatness. These results show that the maximum gain which is the problem of the conventional product is improved 6 ㏈ from 35 ㏈ to 41 ㏈, and gain flatness is also improved 17 ㏈ from 22 ㏈ to 5 ㏈.
