Patent ID: 8598962

Claim:
A method, comprising: modeling a first connection chain configured to carry radio-frequency signals between a first port of a radio-frequency integrated circuit package (RFIC package) and a first port of a printed circuit board (PCB), the first connection chain including a first package pin of the RFIC package; modeling a second connection chain configured to carry radio-frequency signals between a second port of the RFIC package and a second port of the PCB, the second connection chain including a second package pin of the RFIC package; modeling a third connection chain between the RFIC package and the PCB, the third connection chain including: a third package pin of the RFIC package in a vicinity of the first and second package pins; and a capacitor of the PCB coupled between the third package pin and a reference voltage of the PCB; and selecting a capacitance of the capacitor of the PCB based on the modeling.
