i have a sinusoidal signal of 2volts and 50ma current. i need to amplify the signal to get 1.5watt power

What have you decided, so far?
If you have available 1.6 watts and want to make an output with 1.5 watts, which configuration would probably work?

Hello,

What will the frequency?
1mhz is 0.001 Hz and 1Mhz is 1000000 Hz.

yeah, 1 milli Hz would be interesting challenge.

sorry for lame details.. i mean 1Mhz (10^6) and i need to get 1.5 watt nearly. I built a sinusoidal oscillator of 1 Mhz and signal is given to buffer and then CE amplifier, then it gives a 50mA, 2 p-p volt sinusiodal. how to amplify signal to get 1.5w power.

the textbook on transistors should have a chapter on amplifiers

although...
1.5 Watt divided by 400 mA is equal to 3.75 Volts

Generally speaking... thus far your ability to present information in clear and organized manner IS SO BAD, that I don't really care to even try to participate.
