Sige Bicmos Process, The Ku-band Low Noise Amplifier And Mixer Rfic Design

With the rapid development of technology, the size of wireless communication system is becoming more and more small and it's function is becoming more and more integrated. System on Chip (SoC) has become the main focus of the area of wireless communication.In this thesis, a 12.25GHz-12.75GHz low noise amplifier (LNA), and an active double-balance mixer ,which are used in the RF front-end of the Ku-band DVB-S receiver ,are analyzed and implemented using JAZZ 0.35μm SiGe BiCMOS process, which are prepared for the full integration of Ku-band DVB-S receiver.In the first, the development and trend of SiGe BiCMOS RFIC home and abroad are introduced, then, JAZZ 0.35μm SiGe BiCMOS process component and the relationship between component model and circuits design are introduced. After that separately the basic design theories and detail design processes of LNA and active double-balance mixer, including the schematic circuit simulation and the design and optimization of the layout were dissertated. The above design work was summarized at last.The LNA which designed in this paper achieved 3.75dB³.9dB noise figure (NF) and 15dB power gain in the pass band 12.25GHz-12.75GHz, and the input and output match S₁₁,S₂₂ are less than -10dB. The power dissipation of the LNA was merely 19.2mW.The active mixer designed in this paper achieves a 6.5dB double side band noise figure, a 8dB power gain,an IIP3 of -5.1dBm, with only 36mW power dissipation and 0.9×0.9 m² chip size.
