Abstract:
1. A tile array power amplifier (PA) module for use in a phased array comprising: a module with a radio frequency (RF) side and a direct current (DC) side, a top edge, a left edge a bottom edge and a right edge; a first PA die mounted to the RF side of the module adjacent the top edge and the left edge; a second PA die mounted to the RF side of the module adjacent the top edge and the right edge; a third PA die mounted to the RF side of the module adjacent the left edge and the bottom edge; and a fourth PA die mounted to the RF side of the module adjacent the right edge and the bottom edge; a first RF input connector mounted on the RF side between the first PA die and the left edge configured to deliver a first RF input signal to the first PA die; a second RF input connector mounted on the RF side between the second PA die and the right edge configured to deliver a second RF input signal to the second PA die; a third RF input connector mounted on the RF side between the third PA die and the left edge configured to deliver a third RF input signal to the third PA die; a fourth RF input connector mounted on the RF side between the fourth PA die and the right edge configured to deliver a fourth RF input signal to the fourth PA die; a first RF output connector mounted to the DC side and configured to output a first amplified signal from the first PA die; a second RF output connector mounted to the DC side and configured to output a second amplified signal from the second PA die; a third RF output connector mounted to the DC side and configured to output a third amplified signal from the third PA die; and a fourth RF output connector mounted to the DC side and configured to output a fourth amplified signal from the fourth PA die.
