Assignments:

 

·        Assignment #1: Create an ADS project by following Demo.  Hand in a brief report (max. 5 pages) including a schematic design, a momentum layout, and the results (S-Parameters). (Due on Oct 9th @ 5pm by email)

 

·        Assignment #2: Follow the “Approximate Graphical Synthesis” (handout) method to design a 50 Ohm microstrip line at 10 GHz.  Given the substrate (SiO2) thickness, h, is 500 um and the substrate permittivity (er) is 4.  Assume the metallization layer is a perfect conductor.  Use ADS to optimize the transmission line to be 50 Ohm +/- 1% at 10 GHz.  Hand in a brief report (max. 5 pages) including analytical calculation, a momentum layout, an impedance (Zo) vs frequency graph, and a short discussion on the results obtained. (Due on Oct. 30th by email – jay.sing@gmail.com) NOTE: in step (b) fix the value of Zo, in step (d) fix the value of er.

 

·        Assignment #3: Use the transmission line obtained in Assignment 2, match the LOAD (15 - j50 Ohm) to the characteristic impedance of the line.  It is desirable to do this to obtain the maximum power transfer between the source and the load.  Assume lossless transmission line, you can use any techniques to match the line (single stub matching technique is one method, refer to chapter 9 in “Field and Wave Electromagnetics” by Cheng), provided that the reflection coefficient (S11) looking into the line has to be below –15 dB at 10 GHz.

Hint:  Use “tune parameters”  in the schematic window to make the tuning easier.  Press the button and then select the parameters you want to tune on the schematic, ie, the length of transmission line.  If short circuit stub is used for matching, remember to ground the short circuit stub in the layout window.  (Refer to chapter 9 in “Field and Wave Electromagnetics” by Cheng for preliminary calculation designs)

 

Compare the results obtained from the schematic to the layout.  Include in the report (max. 8 pages) the schematic design, layout design, impedance vs. frequency graph, and S11/S21 results. (Due on Nov. 19th by email – jay.sing@gmail.com)
