Abstract
A balun design incorporating the functions of a splitter (combiner) which can be employed in a high power amplifier circuit configuration. The balun is formed of a dielectric multilayer board with conductor patterns on each conductor pattern layer. The balun includes the propagation of a half of an input signal to an in-phase output terminal, and also propagating a fourth of the input signal to first and second opposite-phase output terminals, the signal propagated to the first and second opposite-phase output terminals lagging 180 degrees behind the signal propagated to the in-phase output terminal. The balun provides the output signals at the first and second opposite-phase output terminals 180° out of phase employing through holes in the main line and coupling lines for promoting electromagnetic coupling therebetween.
