Consider the following statements regarding the load matching and impedance measurements:
1. A mismatched load can be property matched to a line by inserting prior to the load a transmission line \frac{\lambda}{4} long.
2. For matching of 120 Ω load to a 75 Ω line, the quarter-wave transformer must have a characteristic impedance of 190 Ω
3. The main disadvantage of single-stub matching is that it is a narrow-band or frequency-sensitive device
Which of the above statements are not correct?
