Zusammenfassung: | Apparatus and methods for amplifier linearization are disclosed. In certain embodiments, an RF amplifier includes an RF input terminal that receives an RF input signal, an RF output terminal that provides an RF output signal, a gallium nitride field-effect transistor (GaN FET) having a gate connected to the RF input terminal and a drain connected to the RF output terminal. The GaN FET amplifies the RF input signal. The RF amplifier further includes a gallium arsenide field-effect transistor (GaAs FET) having a gate connected to the RF input terminal and a drain connected to the RF output terminal. The GaAs FET is operable to linearize the GaN FET. |
