Ludwig Department of Electrical and Computer Engineering Worcester Polytechnic Institute Worcester, MA 01609 copyright 2009, R. Ludwig Copyright, 1998 R. Ludwig ECE3113_L21 2 Objectives What is the general 2-element matching approach? What is the advantage of higher element matching networks? How are microstrip line matching networks implemented? ECE3113_L21 3 There are two strategies A) Source impedance -> conjugate complex load impedance B) Load impedance -> conjugate complex source impedance ECE3113_L21 4 A) General two-element approach 0.2 . 2 0.2 .5 .5 0.5 1.0 1.0 1.0 2 . 2 .0 2.0 5 . 5.0 5.0 .5 0.5 0.5 . 5 2 . 2 . 0 2.0 2.0 . 2 0.2 0.2 .5 .5 0.5 1.0 1.0 1.0 2 . 2 .0 2.0 5.0 5 . 5.0 0.5 . 5 . 5 0.5 2 . 2 . 2.0 2.0 0.2 . 2 0.2 .5 .5 0.5 1.0 1.0 1.0 2 . 2 .0 2.0 5 . 5.0 5.0 .5 0.5 0.5 . 5 2 . 2 . 0 2.0 2.0 1- 1 2- 2 3- 3 4- 4 5- 5 6- 6 70- 7 80- 8 90- 9 100- 1 110- 1 1 12- 1 2 1 3- 1 3 1 4- 1 4 1 5- 1 5 1 6- 1 6 1 7- 1 7 180 . 1 . 1 . 2 . 2 . 3 . 3 .0 4 . 4 .0 5 .0 5 .0 6 .0 6 . 7 .0 7 . 8 .0 8 .0 9 0.09 . 1 0.1 . 1 1 0.11 . 1 2 0.12 . 1 3 0.13 . 1 4 0.14 . 1 5 0.15 . 1 6 0.16 . 1 7 .1 7 . 1 8 .1 8 .1 9 .1 9 .2 .2 . 2 1 .2 1 . 2 2 . 2 2 . 2 3 . 2 3 . 2 4 . 2 4 0.25 0.25 . 2 6 . 2 6 . 2 7 . 2...
