Abstract


RF front-end pre -stage circuit radio receiver system is an important part of the direct impact on the overall receiver performance . In different applications , the design of the RF front-end has a different focus consideration of different communication systems , the RF front-end circuitry is not copied . RF front-end circuit has been the focus of the study of the various agencies , put a lot of manpower and resources . This paper conducted a detailed exposition of the basic theory of the RF front-end design , detailed analysis of the various devices throughout the RF front-end link . On this basis , the design used in the the special band RF front-end circuit . In the design, selection of a low noise LNA die , with a minimum noise matching techniques , to achieve a low noise amplifier of the band , and the case guarantee its gain minimizes the front stage of the noise coefficient ; use LC devices , build their own RF filters and IF channel selection bandpass filter ; combination of overall demand , the choice of a suitable RF amplifier , mixer , controllable gain amplifier chip , the dynamic range of conversion and control functions . Finally, the PCB plate making , processing and RF front-end circuit kind and debug , test , so that the entire circuit to work , get better test results : the noise figure of 1.56dB, the maximum gain of 60dB and other indicators corresponding requirements .
