US 2026/0254704 A1 · APPARATUS AND METHOD FOR BIDIRECTIONAL VECTOR MODULATING

Abstract

A bidirectional vector modulation apparatus capable of modulating vector signals transmitted in both directions is disclosed. The disclosed bidirectional vector modulation apparatus separates an input vector signal into a signal vector component and a carrier vector component, modulates the signal vector component and the carrier vector component respectively by activating or deactivating modulation circuits using current control, and then recombines the modulated components to generate a modulated vector signal. The bidirectional vector modulation apparatus may be applied to communication devices or radar devices, and provides an advantage of enabling simplification and miniaturization of the modulator structure compared to conventional modulation apparatuses.
