HMC797APM5E with HMC980

Hi, 

There are 2 cases in which I will be driving HMC797APM5E. 

Case 1

I will be driving HMC797APM5E under the power compression mode. In this graph, Idd is around 530mA. 

Case 2

HMC797APM5E is still operating in the small signal mode. The Idd will probably be as what is stated in the datasheet (400mA)

I will also be using HMC980 for the power sequencing of  HMC797APM5E.

How should I set my Rsense, based  on Idd of 400mA (small signal mode) or 530mA (power compression mode?
