abstract = {In this paper, the impact of the nonlinear
characteristic of the varactor capacitance on the
intermodulation distortion (IMD) profiles of voltage controlled
impedance transformation networks, is presented. A test set-up
for dynamically measuring the Taylor series expansion
coefficient is proposed, able to be extended to the evaluation of
load-based envelope tracking transmitters (ET). An antiseries
or back-to-back cathode configuration was implemented in
order to minimize the IMD contribution. Measurements and
simulations with a two tone signal validate this proposed
topology for applications in high efficient load-modulated
power amplifiers.},
