A high linearity push-pull cascode amplifier is described. The amplifier is operable to provide a high output impedance through a step-up of a first transistor having a first transistor type and a second transistor having a second transistor type, wherein the second transistor type is different from the first transistor type. The first transistor and the second transistor are coupled in a cascode configuration. The first transistor and the second transistor are coupled together via a capacitor coupled to the input and share a common current path as a push-pull current multiplexed common-gate low noise amplifier with wideband input matching. 描述了高线性度推挽式共栅放大器。放大器用于通过具有第晶体管类型的第晶体管的推级和具有第二晶体管类型的第二晶体管的拉级提供高输出阻抗，其中第二晶体管类型不同于第晶体管类型。第晶体管和第二晶体管在共栅配置中相耦接。第晶体管和第二晶体管经由耦接到输入的电容器耦接在起，并共享公共电流路径，作为具有宽带输入匹配的推挽电流复用共栅低噪声放大器。
