I am designing an power amplifier for radar using HMC7929LS6. Can I use for biasing the HMC980 when the amplifier is saturate?

 

The time to bias sequency to achive de Idd=1200 mA is 300 microsecond to turn ON. Then after 200 microsecond the RF signal is ON and the amplifier will be satúrated Idd>1500 mA, and then after 1msec RF will be off and the turn off sequency start.
