Abstract
A system for power amplification is presented. A tile array power amplifier (PA) module for use in a phased array includes 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. Four PA dies are mounted in each quadrature of the RF side of the module. RF input connectors are mounted on the RF side to bring RF inputs to the PA dies. RF output connectors are mounted to the DC side to output amplified signals from the PA dies. The PA dies are formed, in part, with gallium nitride (GaN) and are mounted to the module in such a way that the tile array PA module is able to generate about 100 watts of RF power and dissipate about 200 watts of heat while amplifying signals over 10 GHz.
