Hello. I'm a system designer.

 

I'd like to use HMC-ALH382, HMC-ALH476, HMC598, HMC442 for making RF system.

 

Above chips need two voltage supplies, VDD and  VGG.

 

When I read "MMIC AMPLIFIER BIASING PROCEDURE", VGG shoud be on befor VDD is on. Is it right?

 

If I ignore bias sequence like VDD and VGG are on at the same time , Will something occur? chip would be damaged?

 

These chips GND are connected PCB ground.

 

Thank you.
