1. Examine different commonly-available coaxial cables:

Data:

Dielectric Properties

Assume the conductors are made of copper.

1. Find the characteristic impedance and R,L,G,C values of each cable (write a matlab program or program your calculator), the wavelength, and the velocity of propagation.
2. Find the attenuation constant of each cable. If you have a 6' length of cable, approximately which frequency can each cable be used without losing more than 10% of the magnitude of the voltage signal through the cable?
3. How important is the type of metal used for the conductor? (This is a qualitative question … you may try other types of metals, to give relative performance, or adjust the values of Rs to show change in effect.)

2. Describe how to analyze a lossy transmission line using the Smith Chart.
