| Abstract: | The theory of receiver linear dynamic range is discussed.The cause of the non-linear distortion for a receiver and its influence on a system is analyzed.The most commonly used 3 linearity characteristics,1 dB compression point,third-order intercept point,and third-order intermodulation are presented.Based on the engineering practice,a design method of the linear dynamic range for a receiver and its expansion method for a system are given. |
