Q308
Consider the following statements regarding the load matching and impedance measurements: 1. A mismatched load can be properly matched to a line by inserting prior to the load a transmission line /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?
