gain − bandwidth transistor

hi...anyone know about this term? actually i want to design power amplifier at 2.4GHz...so need to select the proper transistor...is it true transistor must i choose at least has Ft=24GHz...? confius..

another problem is about transistor?
i confius with terms rf transistor,microwave transistor n power transistor? so wht the transistor for power amplifier?

transistors gain product bandwidth

usually, For PA designing, the Ft is not the higher the better, for CMOS technology, higher ft means thinner OXide. and lower break down voltage.

For PA we hope high breakdown voltage and reasonable Ft
that's why LDMOS is available for PA design
