1 Computer Engineering and Applications 230037 PLA Electronic Engineering Institute, Anhui, Hefei, 230037,China Jia Feng, Yang Ruimin. ADS design and simulation of radio receiver front-end .Computer Engineering and Applications Abstract: As an important part of the RF signal analyzer, the RF receiver front-end plays a decisive role in the measurement of the RF signal. This paper builds one kind of 860 ~ 960MHz RF receiver front-end system simulation platform of RF signal analyzer using the ADS software. The pre-LNA was used to reduce system noise, and AGC was used to achieve a large dynamic range of the RF receiver front-end in the design. The gain, noise figure, sensitivity, dynamic range and other indicators of RF front-end of the design were calculated, and simulated by the software simulation tools. The simulations show that the RF front-end designed in this paper meets the requirements of the design.
