Abstract
A power amplifier includes a transistor operating in a range of frequencies from a lower operating frequency to a higher operating frequency to provide a relatively linear gain between the lower operating frequency and the higher operating frequency, an input transmission line circuit coupled to a gate terminal of the transistor, and an output transmission line circuit coupled to a drain terminal of the transistor. The input transmission line includes an inductor-capacitor (LC) circuit that resonates at a first resonant frequency equaled to or higher than the higher operating frequency. The output transmission line includes an inductor-capacitor-inductor (LCL) circuit and a capacitor-inductor-capacitor (CLC) circuit. The LCL circuit resonates at a second resonant frequency equaled to or lower than the lower operating frequency. The CLC circuit resonates at a third resonant frequency equaled to or higher than the higher operating frequency.
