Abstract : The objective of this effort is to produce a transistor capable of delivering 50 watts of output power at 500 megahertz with 10-dB power gain and 50-percent efficiency. The objective will be achieved by using a metal-oxide-metal overlay structure employing integral leads. A proposed structure with the new device geometry is presented. Design characteristics are described. The advantages of employing metal-oxide-metal and integral lead technology are shown. Device development is detailed to illustrate the processing technology that has been performed on a small-area device employed as a test vehicle. A test metal-oxide-metal structure was fabricated, tested, and subjected to high-temperature testing. Results show that the silicon dioxide is an excellent dielectric for the formation of an MOM structure. The proposed package design is discussed and illustrated.
