ADG902 - Dynamic power consumption

Hi,

 

Where I can find any information about dynamic power consumption of the SPST RF switch (ADG902) ?

 

I'm planning to use this switch to modulate binary data with OOK. Data rate will be 5Mbit/s and carrier about 100 MHz. To estimate consumption of this switch I need like P=alpha*Vdd^2*f+Ps where :

 

P : total power consumption

alpha : constant factor for dynamic power

f : switching frequency

Vdd :  supply voltage

Ps :  static power

 

I know f, Vdd, Ps (from datasheet) but I need alpha. I can get it with measurement by I don't wanna buy eval board at pre-design stage of the project.

 

Kings regards
