Abstract


Ultrashort wave and microwave communication electromagnetic environment is deteriorating , and a variety of military and civilian signal caused the radio spectrum band is quite crowded , and a great interference to the reception of weak signals in long-distance . These strong electromagnetic interference saturation occurs, often resulting in the front end of the broadband receiving device blocking and intermodulation interference , seriously affecting reception quality, therefore a great need for the performance of the receiver to the desired signal received in a communication system , especially non- cooperation The radio signals are processed . This paper received signal in the complex electromagnetic environment technology to conduct in-depth research to find effective design , developed with the characteristics of high sensitivity , large dynamic range , low noise , low false 400 ~ 2700MHz broadband communications receiver , the whole program as well as the key technologies involved have some innovations. First 400 ~ 2700MHz broadband communications receiver main technical indicators are in-depth analysis of the receiver design , and implementation of key technologies , and should pay attention to the problem of , given a system of testing and analysis of results , and finally This paper summarizes the work done in the future to further refine and improve prospect .
