[NLRS] RA30H2127M FET RF Module Idle Current?

Thinking about whipping up a medium power amplifier for 222 MHz.
Thinking about using the RA30H2127M RF Module. It looks like at
(basically) minimum power output, the module draws an Idd of about 5A
and about 6.5A at maximum output. So, if I want to use this as a
linear, should I adjust Vgg to get 5A with no RF drive? I am guessing
that might be the way to set it for linear operation, based on the 3W 10
GHz PA I just built. It uses a FET as well and I set idle current to 2A
with no drive and it draws about 2.5A at max power out, so it appears
the Idd at idle is not too far from Idd at max power to make it linear.
