Hi,
i'm using a 100 MHz signal generator with maximum output of -13dbm, what amplifier design do i use to get 12v output?
thank you...
 

100 MHz signal bandwidth normally implies 50 ohm impedance matching. 12V can mean 12 V into 50 ohm load (12 Vrms, Vp or Vpp ?) or 12 V unloaded output voltage. Depending on the intended generator output waveform, a more detailed amplifier specification should be given. E.g. do you need DC capability?
 

You can use a Monolithic Amplifier as MAR-8 which can give +12.5 dBm at the output from the available input signal.

This circuit is 50 ohms input/output and requires minimum number of external components.
Can be DC supplied at 12V using proper bias resistor.
 
the signal is sinusoidal, i need to amplify it to 12Vpp then transmit using an antenna (50 ohms)

The usual specification for a RF amplifier would be +26 dBm Pout in this case. There are various amplifiers available on the market. If it's small bandwidth (you didn't tell about), it can be build from discrete transistors rather easily.
