DOI: 10.1109/tcsii.2021.3113757
Abstract: Uniplanar wideband high-selectivity filtering full-band-isolation baluns are presented in this article utilizing two different types of out-of-phase matching phase shifters. To obtain high-selectivity performance, half-wavelength open-circuit stubs are introduced. In addition, a single resistor is… read more here.
