Question 1
A signal transmitted from an Earth station bounces back from a geostationary satellite, with an altitude of 35864 km from the Earth surface. The range from the Earth station is 38200 km. the round trip time is about (excluding processing delays and assuming c = 3 X 
m/s)
m/s)Question 2
A lossless transmission line with characteristic impedance Zo = 50 ohms is 30 m long and operates at 2 MHz. The line is shorted at the load, if the phase velocity is 0.6 times the velocity of light, the input impedance of the line is:
Question 3
The VSWR of a microwave unit is 1.5, the return loss is:
Question 4
Using a quarter wave transformer of characteristic impedance 1 
, a load impedance of 100 
will be transformed to an input impedance of value
, a load impedance of 100 will be transformed to an input impedance of valueQuestion 5
