i am using a function generator at frequency around 1Mhz, but the generator's maximum output power is 20mW and maximum current output is 3mA !!!
i need at least 1 W power. what would be a good solution?
 

Simplest solution could be to use a N type FET with its drain pulled up(with the help of resistor) to VCC and source to ground. You can drive it gate with FG and get the output from drain. In this circuit your output will be inverted.
