A complete design and implementation procedure is proposed to reduce the design cycle. Design example using FR4, covering from 900 MHz to 4 GHz, is demonstrated. By using the stripline structure and vias, coupling between different stages is significantly reduced. The new design procedure has been verified by simulation and measurement on several examples.Abstract i Table of Contents iii List of Figures vi 1 Introduction 1 2 Canonical Frequency Responses 9 2.1 Maximally Flat Function . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 2.2 Equal-Ripple Function . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 2.3 Elliptic Function . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11 3 Low-Pass Filter Design 13 4 Band-Pass Filter Design 16 5 Equivalent Circuit Analysis 19 5.1 Design Example for WLAN . . . . . . . . . . . . . . . . . . . . . . . . . . . 27 6 Implementation Considering Parasitics 29 6.1 Implementation Example for WLAN . . . . . . . . . . . . . . . . . . . . . . 33 7 Implementation Example for GSM 900 35 8 Conclusions 422944114 bytesapplication/pdfen-US集總元件濾波器lumped-elementfilterthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/58817/1/ntu-93-R91942052-1.pdf
