  • Package with integrated pre-match circuit and harmonic suppression
    Patent number: 9048232
    Abstract: A package is connected at a first side to a printed circuit board and with a die fixed to it on a second side opposite to the first side. The package has an integrated pre-match circuit to provide an impedance match for a signal to be sent to a circuit external to the package. The signal has a predetermined main frequency component. The pre-match circuit has a pair of transmission lines and a pair of stubs on a predetermined layer of the package and connected to the pair of transmission lines. The pair of stubs have a length such as to form a short circuit for an harmonic frequency of the main frequency component in the signal.
