Band pass filter as filter a important part, its application is very broad, so for the design of the people he has received wide attention. This article from the basic concept of filter to the design method according to the filter nov.18, using some of the previous data obtained, through instance of the research, the design of simple design out of the band filter. And then put a circuit design in ADS software on the simulation, the last of result and through the use of signal processing MATLAB7.0 toolbox of special filter, analysis tools fdatool design compared the filter, and concludes that the validity of the proposed method. Short wave radio station is wireless communication equipment of important parts, this paper designs a shortwave radio band filter based on MATLAB simulation theory first and the spectrum analysis, and then the circuit simulation based on ADS, and got the circuit structure and parameters. Among them, in view of the low noise amplifier band filter design problem with the problem of ADS Agilent company software design and production, basic reach the predetermined specifications.
