This paper proposes the frequency multiplier using diplexer based on composite right/left-handed (CRLH) transmission line with dual band characteristic. The diplexer is separated the output signals of harmonic generator, which is generated the harmonic signals using nonlinear device. The diplexer consists of the inphase power divider, 0°/90° phase controller and dual-band quadrature hybrid coupler...
In this paper a new strategy for designing dualband composite right and left handed (CRLH) structures based on lumped elements is introduced. By using the presented formulars the desired metamaterial devices become easily scalable to arbitrary frequencies as the parasitic elements of the lumped components are considered resulting in three design guidelines. The practical use is shown by a dualband...
The six-port phase correlator is composed of three 90?? hybrid couplers and a Wilkinsion power divider. In this paper, various six-port phase correlators with Wilkinsion power divider, 90?? hybrid coupler and/or 180?? rat-race ring coupler were designed and simulated at the center frequency of 2.5 GHz. The simulation results show that the six-port correlator structure with one 90?? hybrid coupler,...
