Abstract:In this paper, an improved wideband millimeter-wave 180 • hybrid is proposed and a novel W-band broadband single balanced mixer based on the new hybrid is presented. The proposed hybrid consists of a standard waveguide to suspended coplanar waveguide (SCPW) transition and a SCPW to suspended stripline transition. According to the inherent electromagnetic field characteristics of the two transitions, the proposed hybrid achieves good performances of broadband phase, power distribution and isolation. The simulat… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
