Dynamic load modulation of high power amplifiers with varactor-based matching networks
Paper in proceeding, 2009
In this paper, the results of dynamic load modulation
on a high power amplifier is shown with experiments. A
simple static nonlinear model is used as an inverse model, and
by dynamically controlling both the input signal to the power
amplifier and the load impedance, high efficiency operation of
the power amplifier is achieved. The modulated measurements
show the feasibility of dynamic load modulation for practical
high power, high frequency applications.
