VBias
V_BIAS and V_D are separate connections on the
evaluation board to give the option of varying I_D
without changing R4. They can be connected
together to a single voltage supply during the
measurement and in the final layout
implementation of the PCB. If two different voltage
supplies are used then apply V_D first and then V_BIAS
to turn on the LNA. To turn off the LNA disconnect
V_BIAS first and then V_D. R3 is varied to obtain
different levels of gain. R4 is varied to change the
drain current I_D.
