I need major help with either or both of these.
1) A 60 ohm lossless line operating at 5MHz is terminated in a load that consists of a 60 ohm resistor in series with a variable inductor. Find the value of inductance that will produce standing wave ratio of 3 on the line, and calculate the corresponding complex reflection coefficient at the load.
2) A 100-MHz radio station uses a 75 ohm transmission line between the transmitter and an antenna with input impedance of 100 ohm. Design a (lamda/4) transformer to match the antenna to the line. If the quarter-wave section uses a two-wire line with spacing of 1 cm and polyethylene as a dielectric, determine the metric length of the section and the radius of the wire conductors.
