HMC981LP3E enable pin voltage

Hello,

 

I am using the HMC981LP3E bias controller to control the HMC8410LP2FE LNA and I am wondering if I can use a 1.8V GPIO to control the enable pin on the bias controller.  The datasheet stated that the minimum enable input threshold is 1.4V but there's no maximum threshold.

 

Also, if it's not too much trouble, can you do a sanity check on my schematic too?

 

Thanks,

 

-Andrew
