I plan to use HMC903LP3E as front end low noise amplifier and would like to know what is best bias condition for this amp? datasheet graphs are based on Vgg1 and Vgg2 open?
-This is self biased amp meaning that Vgg1, Vgg2 are set internally within the device therefore you are right, leave them open and set Vdd1=Vdd2=3.5 V for Datasheets guaranteed performances.
-When you say 'for the best performances', do you have some special requirements in terms of NF, Gain, IP3, Power consumption..?
I've moved your question regarding the HMC903LP3E to the RF and Microwave community. Someone here should be able to assist you.
