Title: problem about large signal and small signal
Post by dragonnj on Nov 15^th, 2006, 7:20pm

it is said to design PA should use large signal S-parameters, but in another book(Mihai Albulet's RF Power Amplifiers),it is said that "There is no evidence of successful use of large-signal s-parameters in
designing RF PAs above a few watts of output power."

I just wonder what is large signal S-parameters? what is the difference between large signal and small signal? and how to use large signal in my PA designing?

thanks

Dragon
