helping to know some facts about rf transistor designing

hi all.
i want to know some basic information's about designing multistage rf transistor amplifier...
in the beginning i made 3 stage transistor(2n3904,2n3904,2n2222) 27 MHz class a amplifier, am modulation (vcc 12V),
_i amplified the rf signal from 50 mV to 400 mV,is this value good or bad?

_how is the best value of signal voltage in the 3 stage can i arrived to it?

i have transistor (2n3553) can i use it as class a transistor or power transistor?

in the power transistor, how i can calculate the RFC value that connected between vcc and collector?

i based in test on test board, is this true or false?

i think i'm heavy, but really very need to know this information's...

thank's in advance
