Abstract
A multi-finger transistor includes a circuit suppressing a variation in voltage current distribution. The circuit connects gate fingers () to each other, or source fingers () to each other in a region which is located outside an active region () and on a side where a drain pad () is disposed. The multi-finger transistor is configured to be linearly symmetric with respect to a direction of propagation of a signal from a gate pad () at the position of the gate pad ().
