Abstract
An integrated circuit is wire bonded in a manner such that there is consistent RF performance from integrated circuit package to integrated circuit package. Bond distances within the integrated circuit are measured, each corresponding to a wire bond to be formed. An area under a hypothetical wire bond profile is calculated as a function of the bond distances, a baseline wire length, and a baseline loop height. A wire is bonded across a given one of the bond distances to form a given one of the wire bonds. A wire bond profile for the given wire bond is provided having an area thereunder that is substantially equal to the calculated area.
