PURPOSE: To determine the difference of signal path length by unit gate width only by a method wherein a gate wiring is provided in the direction of a drain bonding pad from a gate bonding pad, and a plurality of unit transistor gates are formed in pectination shape almost vertical to a gate wiring.
CONSTITUTION: A gate wiring 7 is provided on the region atarting from a gate bonding pad 1 the direction of a drain bonding pad 2. A unit gate 3 is formed in pectination in the direction vertical to the gate wiring 7. Sources 4 and drains 5 are formed, and each drain 5 is connected by an air bridge wiring 6. The signal inputted from the gate bonding pad l is distributed to each unit transistor through the intermediary of the gate electrode 7, the signal is amplified, gathered and propagated as an output signal. The generation of phase difference of the signal amplified in each unit gate 3 is determined by the width only of each unit gate.
