一種疊接串聯式多厄悌功率放大器包含第一共源極放大器;第二共源極放大器;耦接於該第一共源極放大器與該第二共源極放大器間之相移匹配電路,用來提供90度相移,並僅容許該第一共源極放大器中少於百分之五十之輸出功率被傳送至該第二共源極放大器;串聯於該第一共源極放大器且與該第二共源極放大器並聯之共閘極放大器;以及串聯於該共閘極放大器且與該第二共源極放大器並聯之四分之一或四分之三波長等效電路。該第一共源極放大器與該共閘極放大器構成疊接式主要放大器,並另與該第二共源極放大器構成串聯式次要放大器。
A cascode-cascade power amplifier assembly is provided. Which includes a first common-source amplifier, a second common-source amplifier, a phase shift matching network coupled to the first common-source amplifier and the second common-source amplifier for providing a 90-degree phase shift and allowing less than 50% of the output power of the first common-source amplifier to be transmitted to the second common-source amplifier, a common-gate amplifier which forms a series circuit arrangement with the first-common source amplifier and a parallel circuit arrangement with the second common-source amplifier, and an equivalent quarter-wave or three-quarter wave circuit which forms a series circuit arrangement with the common-gate amplifier and a parallel circuit arrangement with the second common-source amplifier. According to the present invention, the first common-source amplifier and the common-gate amplifier form a cascode main amplifier, while the first common-source amplifier and the second common-source amplifier form a cascade auxiliary amplifier.
