Problem 1. A transmission line connects two chips on a PCB (printed circuit board) that has a thickness of 2 mm and a dielectric constant of 9. The chips communicate at a frequency of 2.4 GHz, and the characteristic impedance of the transmission line is 50 ohms. Design the width, w, of the transmission line shown in the figure below.
