Pulsing 2.4 GHz oscillator

Hi engineers

I need to design af pulsing oscilator to be used for some testing.

It must be able to turn on/off a raw carrier wave of 2.4 Ghz in random intervals of about 2 ms, and it must be possible to adjust the amplitude of the carrier wave.

My idear was to solve it by an oscillator, a PA (power amplifier), and a switch.

The switch is controlled by a little microcontroller, and guides the wave either into the antenna (on) or into a load resistor (off)

I believe Analog Devices has most of the components that I need.

Any one who can recomend some devices for me?
