    The datasheet for this LNA does not give information about the gate bias current. I am designing a gate driver and need to know how much current it will need to source. I assume this is < 1mA, but some data would be nice to have. I do not have a dev board to test.

      Hi Paul,
      

      During validation, while power testing under RF sweep (and over temperature), we observed a nothing above -0.3mA for Igg. From the parts measured, we actually didn't see above -0.23mA but to be conservative I would say -0.3mA is a good number.
      

      Thanks,
      

      DanO
