Biasing HMC633LC4 using HMC981LP3E

I am Planning to use active bias controller HMC981LP3E for biasing HMC633LC4 . Attached schematic is given below

Will the attached Schematic Sufficient for biasing HMC633LC4 or some changes are Required.

The following are the doubts,

1) HMC633 dost not required VG2, But as per the Excel sheet calculation if I don't enter VG2 voltage the calculated R1 value is coming as 10kohm(between pin 1 &2). Should I Add this resistor? As per the datasheet of HMC981LP3E, In Page 17 the recommended R1 and R2 values for HMC633 amplifier is given as open.

2)HMC633 datasheet suggest to increase vary Vg from -2V to 0 

2)On Excel sheet calculation, If I enter VNEG as -2V, then it calculation recommends R4 resistor value as 1.6Mohm(Between pin 9 and 8). Should I add this resistor?

As per the datasheet of HMC981LP3E, In Page 14 Mode selection table shows VNEGFB should be floated to operate in mode1(Depletion Master mode)

3)On Excel sheet calculation, What should be the VGate threshold value i should enter for HMC633? For example if I give VGate threshold value as -1.3 then calculation recommends R6 resistor value as 477ohm(Between pin 11 and 7). Should I add this resistor?
