1. A radio frequency (RF) front end chip in a phased array antenna panel, said RF front end chip comprising:
an oscillator providing an angular speed modulation signal to a quadrature generation block;
said quadrature generation block providing an in-phase signal and a quadrature signal based on said angular speed modulation signal;
a first amplifier receiving said in-phase signal and a data signal, and providing a modulated horizontally-polarized signal;
a second amplifier receiving said quadrature signal and said data signal, and providing a modulated vertically-polarized signal.
