The design of a multi-channel receiver phase shifter based vector multiplier for high performance and low-cost active antenna array is presented in this paper. A receiving array architecture that combines analog beamforming is to offer a solution for the phase array and smart antenna application. In the architecture, a system with simple calibration procedure is presented to decrease the phase deviation...
In this paper, a high step-up converter with coupled-inductor and built-in transformer is proposed. Compared with other converters with coupled-inductor, the built-in transformer introduces a new control variable of the voltage gain which improves the design flexibility and conversion efficiency. Thus, low ratio of coupled-inductor can be selected. Input current ripple is reduced so that the input...
