It includes LNA, mixer, and LO. The LO signal is stablized by an injection-locking oscilla- tor. IF ampli ers and lters are designed to improve the IF signal. This hybrid circuit is implemented FR4 PCB to verify its function.Table of Contents ii List of Figures vi 1 Introduction 1 2 Microwave Ampli er 3 2.1 Power Gain . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 2.2 Stability Criteria . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 2.3 Noises in Components . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 2.4 Noise Figure . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 2.5 Nonlinear E ects . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13 3 Diode Mixer 20 4 Local Oscillator 26 4.1 Injection-Locking Oscillator . . . . . . . . . . . . . . . . . . . . . . . . . . . 30 4.2 Literature Survey . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 34 4.3 Implementation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 42 i CONTENTS ii 5 Conclusions 56 Bibliography 5726171180 bytesapplication/pdfen-US短距通訊系統低雜訊放大器混波器注入鎖相震盪器short-range communication systemLNAmixerLOinjection-locking oscillatorthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/58816/1/ntu-94-R92942064-1.pdf
