Abstract:
A high-frequency circuit, comprising:a switching transistor including a source with a source electrode formed on a source region, a drain with a drain electrode formed on a drain region, and a gate with a gate electrode connected to an effective gate portion divided into a plurality of sections, said switching transistor being configured such that: (1) one of said source electrode and said drain electrode is connected to an input terminal, (2) the other of said source electrode and said drain electrode is connected to an output terminal, and (3) said effective gate portion is connected through a resistance element to a control terminal; and a first additional capacitance element located proximate ends of at least two of the plurality of gate sections and electrically connected between said gate electrode and either of said source electrode or said drain electrode, wherein said first additional capacitance element is formed by physically overlapping said gate electrode and either of said source electrode or said drain electrode.
