DISPOSITIF PASSIF INTÉGRÉ POUR BOÎTIER D'AMPLIFICATEUR DE PUISSANCE RF

摘要

The present invention relates to a radiofrequency (RF) power transistor package. It further relates to a mobile telecommunications base station comprising such a RF power transistor package, and to an integrated passive die suitable for an RF power amplifier package. According to the present invention, an in-package impedance network is used that is connected to the output of the RF power transistor arranged inside the package. This network comprises a first inductive element having a first and second terminal, the first terminal being electrically connected to the output of the RF transistor, a resonance unit being electrically connected to second terminal of the first inductive element, and a second capacitive element electrically connected in between the resonance unit and ground. According to the present invention, the first capacitive element is arranged in series with the second capacitive element.
