Abstract
An input matching parallel inductorwhich utilizes a spiral inductor, and an input matching parallel capacitorwhich utilizes an MIM capacitor, both being constituting elements of an input matching circuit portion, form an input matching parallel capacitorinside an input matching circuit via-holebeing formed by applying a method of surface via-hole to the front surface of a GaAs substrate. A choke inductorwhich utilizes a spiral inductor, and a bypass capacitorwhich utilizes an MIM capacitor, both being constituting elements of a drain voltage feeding circuit, form a bypass capacitorinside a drain voltage feeding circuit via-holeformed by applying a method of surface via-hole to the front surface of the GaAs substrate. A drain voltage terminalis extended by a drawing wirefrom between the spiral inductor and the drain voltage feeding circuit via-hole
