2 Using Line Calc to design microstip lines Go to Rogers Corporation web site, then go to Advanced Circuit Materials link and find the appropii ate substrate parameters (e, tano) for RT Duroid5870 and RO 4003C. For each find two thicknesses of the substrate 62mils and 32mils, loz EDC copper. If the thickness of the dielectric is not available exactly as specified, select the closest value commercially available. This means that you will have to find four different laminates. To find these parameters, look at the High-Frequency laminates Product selection guide. In a table or a pargraph, write the specifications of the substrates you found. 1. Start ADS. In schematic window, click on Tools, Line Calc, Start Line Calc. LineCalc window should open. Choose the microstrip line (MLIN) 2. Design a 5012, 1012. 100 and 90, 10 line. for the substrate RT/Duroid RO4003. Use the same substrate as one of the two RO 4003 found above. Hint: The degrees in Line Calc represent the electrical length of a line. Electrical lenght is calculated as 2d uhere is the wavelength. and l is the actual lenght of the line. X = T - , where c is the speed of light, f is the frequency and eeff is the effective dielectric constant. 3. Design a 5012, 1012, 100 and 90 line. 10 for the substrate RT/Duroid 6002, select the height and copper thickness of your choice. 4. Use equations for microstrip lines from Ulaby's book (see Handout or Microstrip Lines section of Ulaby, page 62) and Matlab to calculate transmission line impedances. How do they compare to the ones from LineCalc? 2 Using Line Calc to design microstip lines Go to Rogers Corporation web site, then go to Advanced Circuit Materials link and find the appropii ate substrate parameters (e, tano) for RT Duroid5870 and RO 4003C.
