W-Band (92-100 GHz) Phased-Array Receive Channel With Quadrature-Hybrid-Based Vector Modulator.
IEEE Trans. on Circuits and Systems(2018)
摘要
This paper presents a W-band (92-100 GHz) phased array receive channel adopting a power domain vector modulator (VM), which utilizes a 90° hybrid-coupler-based phase interpolator. The quadrature hybrid leverages its inherent functions of quadrature phase splitting and power combining to interpolate phases by combining the weighted signals from variable gain amplifiers in the power domain. Compared...
