Abstract
A phase shifter for a millimeter wave (mmW) communication system including an in phase variable gain amplifier (I VGA) and a quadrature VGA (Q VGA) configured to receive radio frequency (RF) signals, the I VGA and the Q VGA configured to provide a selectable output to primary sides of first and second electromagnetic (EM) elements, respectively, the first EM element configured to provide a single-ended I output and the second EM element configured to provide a single-ended Q output, and a hybrid quadrature generator (HQG) configured to receive the single-ended I output of the first EM element and the single-ended Q output of the second EM element, the HQG configured to provide a combined signal at a desired phase.
