Shared phase shifter radio architecture

A method for phase shifting signals, comprising:

• providing radio frequency (RF) receive signals to an in phase variable gain amplifier (I VGA) and to a quadrature variable gain amplifier (Q VGA), wherein the RF receive signals comprise single-ended RF input signals provided to the I VGA and to the Q VGA and the I VGA and the Q VGA provide pseudo-differential outputs;
• providing a pseudo-differential output of the I VGA to one of a positive terminal or a negative terminal of a primary side of the first EM element;
• providing a pseudo-differential output of the Q VGA to one of a positive terminal or a negative terminal of a primary side of the second EM element;
• steering current through the I VGA and the Q VGA to generate in phase and quadrature signals;
• and
• combining the in phase and quadrature signals from the I VGA and the Q VGA to generate a single-ended combined signal at a desired phase.
