Taken out of context, this statement can cause trouble. There are places where
bi-polar transistors have advantages, but high power ( >+30 to 40 dBm or more)
RF amps isn't one of them.
There's some argument about low phase noise oscillators: with an unbypassed
emitter resistor, they can do very well, because they don't have the 1/f noise
inherent in FETs, especially in GaAsFETs. They certainly have advantages in
mixers in direct conversion receivers.
