Abstract

This paper presents a four-element phased-array re- ceiver which achieves 38% frac tional bandwidth around 55 GHz. Baseband phase-shifting is employed to eliminate wideband phase-shifters, power dividers, a nd quadrature splitters operating at millimeter-wave frequencies. Antenna weighting and combining are accomplished using a highly digital Cartesian phase-shifter and current summation, respectively. Transformer-coupling techniques are introduced in the LNA to simultaneo usly achieve wide band
