Name:_______________________________ EE 4002-2 Final Exam SSN: _______________________ Spring 2003 1. At 2.4 GHz, what is the largest component size that can exist without  needing to use transmission line theory to design or analyze the circuit?  Assume v p  = 0.69c. 2. The leads of a resistor in an RF circuit are 5 cm Aluminum AWG 14.  ( σ AL  = 4.0 x 10 7  S/m).  Compute the DC resistance and the AC resistance and  inductance at 1 GHz. 3. Design an impedance matching network for cordless phone narrow band  circuits at 3.1 GHz that will have a nodal Q of 10.  The load has an  impedance of Z L  = 18 –j35 and the load must be matched to 50  Ω .  There  is no limit to the number of elements you can use.  DO NOT COMPUTE  THE COMPONENT VALUES, but be sure to draw your final circuit with  the component clearly labeled.  Use a smith chart.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
