Hi,
I am reading quarter-wavelength transmission line transformer on an article: The Yin-Yang of Matching: Part 2—Practical Matching
Techniques.
I do not understand the second sentence about 22%. This percentage is regarding to which bandwidth? It gives as an example of the first sentence, i.e. for ratio 6:1, it is narrower? I do not see that from the passage. Could you explain it to me?
Thanks.
.........................
The bandwidth of a quarter-wavelength transmission
line transformer decreases with loads higher or lower
than the desired resistance. The bandwidth is about 22%
for a ratio of 6:1 as with a 300 ohm load in a 50 ohm system.
The bandwidth can be improved by cascading multiple
quarter wavelength transmission line sections. Given
in this section is a simple but effective algorithm for computing
the required characteristic impedance for each
section.
