LMX2541 to generate 400ns RF pulses at 2.4GHz with 50% duty cycle?

I'm looking for some timing diagrams for LMX2541 power on/off using RFoutEN pin.

What are the raise/fall times (lag) of the output RF carrier with relation to RFoutEN signal.

I want to generate 400ns RF pulses at 2.4GHz with 50% duty cycle, would I be able to do this using RFoutEN pin? The ON/OFF power ratio is only around 30dB
