HMC5445 power on sequence

Dear Sir ,

 

HMC5445 has the positive(Vdd) and negative (Vgg) power supply.

Does it need to care about power sequence (Even I knew my working voltage such as vdd=5V/vgg=-1 has the best performance) ?

According to internal document ," MMIC AMPLIFIER BIASING PROCEDURE", that points out it should be adjustment the negative power supply first in procedure .

So could you help me to clarify this question, tks!
