Abstract
The output voltage/current wave forms and load lines of a common emitt er HBT under constant base current and constant base voltage bias cond itions at several input power levels were simulated with a non-linear simulator. The simulated output power characteristics of each set of b ias conditions were compared with measured data. It was learnt that go od gain linearity and good efficiency were obtained across a wide inpu t power range, by using a constant base current bias mode. This is bec ause operation
