Abstract

The present invention relates an ultra-wideband power divider/combiner, and more particularly, to a power divider/combiner that can control the bandwidth of an input or output signal to an ultra-wideband using a short line that is capacitively coupled to a transmission line and has half the length of a center frequency wavelength (λ). The ultra-wideband power divider according to the present invention controls a capacitive-coupling size between the transmission line and the short line having half the length of the center frequency wavelength (λ), thereby accurately setting the bandwidth of an input/output signal to a desired ultra-wideband. Moreover, the ultra-wideband power divider according to the present invention is configured with only said short line that is capacitively coupled to the transmission line, and thus the ultra-wideband power divider can be miniaturized and manufactured at a low cost.
