tube vs sspa comparision

Hi
I wanna to have a precise comparison between "rf tube and solid state amplifiers".
can any one guide me to a useful reference?
tnx

For parameters comparison you can use data for TWT power amplifiers and SS power amplifiers which are produced for satellite communications. Direct comparison of electronics is not possible because of different technologies.

Here is one of articles comparing such amplifiers: http://www.mpdigest.com/issue/articl...eq/default.asp
