Abstract
The present disclosure includes dynamic power divider circuits and methods. In one embodiment, a dynamic power divider includes first and second quarter wave lines that receive an input signal and produce first and second signal on second terminals of the lines. Dynamic power division of the input signal uses a variable impedance circuit between the second terminal of the first quarter wave line and the second terminal of the second quarter wave line. The variable impedance may reduce impedance between two output paths as the input signal power increases or increase impedance between the output paths as the input signal power decreases.
