Abstract

A radio frequency (RF) front end for a communication system includes a phase shifter having 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 I VGA and the Q VGA configured to selectively provide DC current to a low noise amplifier (LNA).
