how to know amplitude voltage output?

hi all...
i have a question and really no one can answer to me to present , i want to ask about amplitude of output signal RF power amplifier,
IF VCC= 12V , i need the output power amplifier is 5 watt (transistor BD135)class C, how is the value of voltage amplitude output...
thank's

hello danfoss
could you upload your circuit image to calculate so better(if i can)?

thank you baby, this circuit is power amplifier for 2n3553 ( 175 MHz and 28 Volt), but i want to use it in 27 MHz and 12 Volt vcc

Hello danfoss
according the schematic that you uploaded we can't find the amplitude with the ac & dc analyse and with small signal so quickly.i think this link can help you on this

ok, in the PDF file, class c simulation, the vc=29.29 volt and Vout=13.47 volt, the dilemma is how can to get vc or vout bigger than vcc?
and what is the component can adjust it?
