1. A radio frequency circuit comprising:
a radio frequency module including a linearizer circuit, the linearizer circuit including a first capacitor and a second capacitor arranged in parallel, the first capacitor having a positive third order derivative of charge with respect to voltage, the second capacitor having a negative third order derivative of charge with respect to voltage; and
a power amplifier circuit including a power amplifier configured to amplify a radio frequency signal for transmission, the radio frequency module configured to reduce intermodulation distortion during operation of the power amplifier.
