Abstract
Aspects of this disclosure relate to a mode linearization switch circuit that can adjust an effective impedance provided to an output of an amplifier. In an embodiment, an apparatus includes an amplifier configured to amplify a radio frequency (RF) signal and a mode linearization switch circuit electrically coupled to an output of the amplifier. The mode linearization switch circuit can include a capacitor, a switch in series with the capacitor, and a series LC circuit in parallel with the switch.
