    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.

    Abstract: A method for dealing with high inrush current when voltage is applied to mixed voltage logic integrated circuits is disclosed. A depletion N-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) or junction Field Effect Transistor (JFET) is added to a linear voltage regulator in mixed voltage logic integrated circuits. The Field Effect Transistor (FET) is utilized to allow the core voltage to come up with Input/Output voltage prior to turn-on of linear voltage regulator. Turn-on state of FET allows the core voltage to rise with Input/Output voltage until the FET threshold is reached across the gate. When threshold is reached, the FET turns off to allow linear voltage regulator turn on and take over supply power.
