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.
