(on the following, v gg1 has to be kept in 3.4v . ) around v gg2 =0v(minimum), the output power and drain current increases substantially. around v gg2 =4v (typical) to v gg2 =5v (maximum), the nominal output power becomes available. b) linear am modulation: by rf input power p in . (on the following, v gg1 has to be kept in 3.4v . ) v gg2 is used to set the drain?s quiescent current for the required linearity.
