Abstract
High frequency amplifier circuitry includes a common-source first transistor to amplify a high-frequency input signal, a common-gate second transistor cascade-connected to the first transistor, to amplify a signal amplified by the first transistor to generate an output signal, a first inductor connected between a source of the first transistor and a first reference potential node, a second inductor connected between a drain of the second transistor and a second reference potential node, and non-linear compensation circuitry connected to a connection node of the first transistor and the second transistor, to compensate for non-linearity of the output signal to the high-frequency input signal. The non-linear compensation circuitry has first rectifier circuitry, a first resistor, a second resistor, second rectifier circuitry, first capacitor and second capacitor.
