Talk:Traveling wave tube amplifier

Suggestions for expansion
Can an expert familiar with the subject add a little about why TWTAs are important? What properties do TWTAs possess (over other types of amplifiers) that makes them ideally suited for the listed applications (in satellite transponders, etc.)? In other words, what was the motivation for the invention of TWTAs, and why does the world still need them? Are they more expensive to manufacture and tune than other types of amplifiers?

Most of the information on this page is already covered at the Traveling wave tube page, I think it should probably redirect there.128.152.20.33 (talk) 22:52, 2 January 2008 (UTC)
