how do i amplify the output voltage of a signal generator?

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.

3W FM Transmitter Amplifier

I use one of these http://www.minicircuits.com/pdfs/ZHL-2010+.pdf to boost my signal generator but as FvM said - it depends on if you only need narrowband.
