Abstract
In this paper, vector modulator which controls magnitude and phase of input signals is proposed. The previous magnitude/phase controlling circuit which is composed of attenuator and phase shifter makes phase/gain cross-coupling. The proposed modulator which composed of low phase shifting attenuator and 0°/180° phase shifter can minimize phase/gain cross-coupling. So the Cartesian coordinate plane of the output signal space can be represented with vector modulator
