Efficient Linearized All-Silicon Transmitter ICs (ELASTx)
Abstract
The Efficient Linearized All-Silicon Transmitter ICs (ELASTx) program developed 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 was leveraged to improve the performance of high-power amplifiers based on other non-silicon technologies, through heterogeneous integration strategies. Significant technical obstacles were overcome including 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.
