Low pass filters are added at output port of each VCO to improve its harmonic rejection. The simulated results for both VCOs are presented and their performances are compared with other VCOs.Chapter 1 Introduction 1.1 Background 1.2 WLAN standards 2.3 The parameters of VCO 4.4 Literature Review 5.5 Overview 7hapter 2 Resonator design 8.1 Introduction 8.2 Substrate-integrated cavity resonator design 8.3 Q-factor 10.4 Unloaded Q-factor 11.5 Q measurement methods 12.5.1 Two-port measurement method [16] 13.5.2 One-port reflection measurement method [17] 16.5.3 Verification by EM simulator 19.6 Design of gap-couple micorstrip resonator 20.7 Substrate-integrated cavity resonator design 23hapter 3 Theories of oscillator design 26.1 Introduction 26.2 Feedback oscillator 27.3 One-port negative-resistance oscillator 28.4 Two-port negative-resistance oscillators 31.5 Noise 33.5.1 The noise models of transistor 35.6 Phase noise 37hapter 4 2.4 GHz VCO using microstrip line resonator and 5.2 GHz VCO using SIW cavity resonator 43.1 Introduction 43.2 VCO design procedure 43.3 2.4 GHz VCO using microstrip line resonator 45.3.1 Transistor and varactor selection 45.3.2 Circuit schematic 47.3.3 The fifth-order low-pass filter 48.3.4 Circuit simulation results 49.4 5.2 GHz VCO using cavity resonator 53.4.1 Transistor and varactor selection 53.4.2 Circuit schematic and simulation results 55hapter 5 Conclusion 62efences 64omponent datasheets 68A) Infineon BFR360F 68B) Skywork SMV1232 76C) Agilent HBFP-0420 80D) Aeroflex MGV-125-20 85E) MAXIM MAX 2750 92F) DELTA DMP-VCX2074UT6 96G) Hittite HMC430LP4 98H) Intersil ISL 3084 1024658235 bytesapplication/pdfen-US#������q���L�a�uvcomicrostrip line利用微帶線共振器設計2.4 GHz壓控震盪器及基板集成共振腔設計5.2 GHz壓控震盪器The design of 2.4 GHz VCO using microstrip line resonator and 5.2 GHz VCO using substrate-integrated waveguide cavity resonatorthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/189018/1/ntu-96-R92943099-1.pdf
