An integrated matching network includes a first die on a substrate, a
second die on the substrate, and a metallization layer on the first and
second dies. The second die has a capacitance, the metallization layer
has an inductance, and the capacitance and inductance together provide a
shunt impedance from the first die to the substrate. The integrated
matching network includes a first die having a power amplifier, a second
die having a capacitor, and a metal interconnect coupled to the power
amplifier and the first capacitor. The metal interconnect has an
inductance. The capacitor and metal interconnect form a shunt impedance.
