| Abstract: | Due to the internal coupling between bonding wires inside RF power amplifiers, the current cross wire arrays become non-uniform, causing individual cells to operate under unequal and non-ideal conditions. Various optimisation approaches enhancing the uniformity have consistently led to improvements in device performance. The consistent performance gains across different methods suggest that a common underlying mechanism or variable may be driving observed improvements. Multiple approaches have been compared to reveal the underlying mechanism. Simulation results show that optimising the bond wire height distribution is most effective from the perspective of a voltage-controlled current source. A uniform voltage distribution over the gate results in increased maximum power output. Furthermore, the current phase of the drain should be aligned to enhance the efficiency. |
