Integrated Design And Implementation Of Miniaturization IF Transceiver

The thesis discusses the current situation and developmental tendency of digital variable polarization detection system.Moreover,we introduce the research direction of variable polarization detection system both domestic and overseas.To satisfy the requirement of the mass and volume in radar guidance system,we managed the design and execution about the four channel intermediate frequency transceiver module in the system.First,the paper introduces the consistence of variable polarization detection system and its operational principle,and then gives the detailed introduction and comparison of two kinds of frequency conversion schemes.Second,by the characteristic of the detection system,the paper analyses the source of C-band hopping system.We analyze the theory and index of frequency source component,the scheme of double loop switching is selected to ensure the frequency agility.We test and analyse the phase noise of output signal by setting up the test platform.At last,a low phase noise and high-speed frequency agility is abstained.According to the actual demand of the detector system,this paper presents the technical parameters of the four channel transceiver,and then the design idea and work principle of the transceiver are introduced,describes the specific process of the frequency conversion completely.After that the design scheme of miniaturization is explored and analyzed,whereby we proposed several schemes to execute the intermediate frequency transceiver module whose effectiveness and feasibility are guaranteed by theory analysis.Finally,we analyze the design of intermediate frequency control unit and indicate that the method which is utilized to control the frequency hopping source module and transceiver.Then the work pattern of system and control byte is specifically given.In addition,we testify the effectiveness of intermediate frequency control unit toward the systematic control through analyzing the wavelet form of simulation.
