E- 8.854 x 10-12 F/m; Ho = 1.256 x 10- H/m; C = 3 x 108 m/s You are asked to troubleshoot a 12 GHz satellite receiver that has a problem with the input matching network. To fix this, assume you are trying to provide a perfect impedance match from the source impedance ( 50 (2) to a real impedance of 90 Q. Use microstrip quarter-wave transformer to achieve this impedance match. The substrate material is 0.381 mm thick alumina ceramic (Er = 10). a) Determine the characteristic impedance of the transformer. Z-=- -2 b) What is the width of the microstrip transformer (in mm)? W = - mm C) What is the length of the microstrip transformer (in mm)? L= mm
