Efficient Linearized All-Silicon Transmitter ICs (ELASTx)
Abstract
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 for future miniaturized communications and sensor systems on mobile platforms. 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 small munitions. The technology developed under this program could also be leveraged to improve the performance of high-power amplifiers based-on other nonsilicon technologies through heterogeneous integration strategies. Significant technical obstacles to be overcome include the development of highly efficient circuits for increasing achievable output power of silicon devices (e.g., device stacking, power combining) at mm-waves; scaling high-efficiency amplifier classes to the mm-wave regime; integrated linearization architectures for complex modulated waveforms; and robust RF/mixed-signal isolation strategies.
