Power Amplifier decoupling capacitor

I am using the ADL5542, RF Power Amplifier. The datasheet mentions the use of 1uF decoupling capacitor at the power supply. Does the value have to be exactly 1uF or something close to it would also suffice? An explanation as to what this capacitor does would be really great. In the absence of this capacitor, how is the performance affected?

 

Thanks.
