Abstract:
1. A semiconductor power device comprising: a flange; a die having a gate, a source, and a drain, wherein the source is electrically coupled to the flange; a drain matching circuit located on the flange having an input, an output and a bias input, the input being coupled with the drain, wherein the drain matching circuit comprises an inductor coupled in series with a first capacitor between the drain and flange and a second capacitor arranged next to the first capacitor, wherein the second capacitor is coupled with the bias input and in parallel with the first capacitor through a second inductor; an input terminal being mechanically coupled to the flange and electrically coupled with the gate; an output terminal being mechanically coupled to the flange and electrically coupled with the output of the drain matching circuit; and an input bias terminal being mechanically coupled to the flange and electrically coupled with the drain through the bias input.
