Efficient Linearized All-Silicon Transmitter ICs (ELASTx)*
Abstract
*Formerly Millimeter-wave All-Silicon Transmitters (MASTR). (U)The goal of the Efficient Linearized All-Silicon Transmitter ICs (ELASTx) program is the development of revolutionary high-power/high-efficiency/high-linearity single-chip millimeter (mm)-wave transmitter integrated circuits (ICs) in leading edge silicon technologies. The high levels of integration possible in silicon technologies enable on-chip linearization, complex waveform synthesis, and digital calibration and correction. Military applications include ultra-miniaturized transceivers for satellite communications-on-the-move, collision avoidance radars for micro-/nano-air vehicles, and ultra-miniature seekers for self-guided munitions. The technology developed under this program could also be leveraged to improve the performance of high-power amplifiers based-on other non-silicon technologies through heterogeneous integration strategies. Significant technical obstacles to be overcome include the development of efficient circuits for increasing achievable output power of silicon devices (e.g., effective breakdown voltage enhancement, power combining) at mm-waves; scaling high-efficiency amplifier classes to the mm-wave regime; robust mixed-signal isolation strategies; and thermal management considerations.
