The multisection tri-plate stripline design exhibits excellent amplitude balance with broadband quadrature phasing (90o) between the output ports. Applications include single sideband upconverters, image rejection downconverters, IQ modulators ... Currently, dealing directly with in-phase and quadrature time series data using the deep learning method is widely used in signal modulation classification. However, there is a relative lack of methods that consider the complex properties of signals. Therefore, to make full use of the inherent relationship between in-phase and quadrature time series data, a complex-valued hybrid neural network ... ….

who are the community Hybrid (3dB) quadrature couplers are used in most reflection-style phase shifters. Quad couplers can be realized as branchline couplers (distributed or with lumped elements), Lange couplers, or other coupled line couplers of many varieties. The bandwidth of the quadrature reflection phase shifter is mostly limited by the choice of coupler, you ...In this paper, a wideband quadrature hybrid coupler is presented.
