Abstract
An impedance transformation network, power amplifier and method for efficiently transmitting an output signal utilizes a series varactor device to provide a variable impedance transformation. The series varactor device may include a number of stacked ferroelectric varactors that function as a variable capacitor to provide the variable impedance transformation in response to the power level of the output signal.
