Using HMC920 for Temperature Compensation

My Amplifier CHA3024 changes its gain as temperature changes. I want to use HMC980 Active bias Controller for maintaining its drain current constant and for sequencing of Amplifier.
But i am not sure that will this active Bias Controller be able to maintain constant gain by monitoring drain current(maintaining fixed Bias point) and mitigate the effects on gain due to temperature changes

I am attaching Datasheets of both Amplifier and Bias Controller.
