Abstract

A field effect transistor (FET) is comprised of a plurality of unit transistors having a common gallium arsenide substrate with an N-type active region. Each unit transistor is comprised of a unit gate, a unit drain and a unit source. The FET is mounted in a flip-chip carrier that connects all of the unit sources together to form a first electrode of the FET. Additionally, the first electrode is connected to ground by the carrier. All of the unit drains are connected together on the substrate to form a second electrode of the FET. The FET is reverse biased to cause a current to flow from the first electrode to the second electrode, whereby the first and second electrodes are a drain and a source, respectively, of the FET.
