Abstract
In RF power transistors, the current distribution along edges of the transistor die may be uneven leading to a loss in efficiency and in the output power obtained, resulting in degradation in performance. When multiple parallel dies are placed in a package, distribution effects along the vertical dimension of the dies are more pronounced. A RF power device (600) for amplifying RF signals is disclosed which modifies the impedance of a portion of the respective one of the input lead and the output lead and redistributes the current flow at an edge of the transistor die.
