Exercise 33

A 50 transmission line is terminated with a resistive load of 120 ft impedance. A generator puts a signal with a frequency of 70 MHz and a power level of 20 dBm into the other end of the line. The line has a velocity factor of 0.8.
(a) Calculate the reflection coefficient at the load.
(b) Calculate the voltage standing-wave ratio at the load.
(c) How much power is dissipated by the load
(d) Design a quarter-wave transformer that could be installed at the load to match it to the line. Sketch the transformer and calculate its length and characteristic impedance.
