Design of a Novel Vector Modulator

Introduction to a vector modulator that controls magnitude and phase of an input signal
October 1, 2001
Technical Feature Design of a Novel Vector Modulator A vector modulator that controls magnitude and phase of an input signal is proposed in this article. The previous magnitude and phase-controlling circuits, composed of an attenuator and a phase shifter, permit phase and gain cross-coupling. The proposed modulator, which is...
