Abstract

The present invention relates to an equivalent circuit of a package ground terminal paddle which is used to mount a microwave integrated circuit, and more particularly, to an approximate equivalent circuit of the package ground terminal paddle by which the expressions of parasitic components can be easily expanded according to the number of gold wires that are down-bonded to the paddle, by introducing an equivalent circuit structure which takes the impedance component output from each terminal as one common impedance component and grounds the common impedance.
