Abstract :
RF multiple-input multiple-output circuits are normally implemented with the beam-forming network between the amplifier and antenna. Here the amplifier is placed between the beam-forming network and antenna, thus improving the performance in terms of power loss and noise figure as well as allowing operation for beam steering or spatial diversity
