We have some questions in the datasheet specification and data.
Supply Current (Idd)
(Vdd = 3.5V, Vgg1 = Vgg2 = Open)
45(typ) 65(max) mA
Current vs. Input Power @ 16 GHz
Q1. "Supply Current (Idd)" , it means the self bias idle current at RF off ?
Is it the variation data ?
Q2. "Vgg1 = Vgg2 = Open" is typo ?
HMC963LC4 is only Vddn.
