Abstract
A microelectronic package having a radio frequency (RF) amplifier circuit and, incorporating harmonic rejection filters and matching circuits integrally formed in the package is disclosed. A harmonic rejection filter may comprise a metal-insulator-metal (MIM) capacitor serially coupled between bond pads disposed on a RF amplifier circuit die, a first wire bond coupling a first bond pad to a package output, where the first bond pad is coupled to the output of the RF amplifier, and a second wire bond coupling a second bond pad to a package ground. The harmonic rejection filter may be appropriately configured to filter one or more harmonics at different frequencies.
