Phased array impedance tuning, secure transmission, and nonlinear spatial intermodulation suppression for next-generation radar and communications systems.
… power amplifier nonlinearities by element-wise impedance tuning between each power amplifier and antenna element to reverse the nonlinear distortion effects. To emphasize the importance of the flexibility that elementwise impedance tuning provides, the analysis of a single-beam phased array …

Real-time adaptive circuitry to support simultaneous radar and communications.
… while maximizing array performance through live impedance tuning and signal equalization. This methodology is demonstrated in simulation with a linear sixteen element array, but it is easily scalable to larger and multidimensional arrays.

Control and in-situ measurement of adaptive and reconfigurable RF systems.
… optimization parameters and implementation of impedance tuning into a metacognition-guided system are examined. Optimization of reconfigurable hardware requires a feedback system to evaluate real-time performance changes and assess the array transmission pattern. To enable this, an in-situ RF …

A FIR Filter Embedded Millimeter-wave Front-end for High Frequency Selectivity
… various high-efficiency techniques such as impedance tuning with a reactive component at a cascoding stage in conventional stacked power amplifiers or load-pull based inter-stage matching technique, rather than conventional conjugate matching, have been applied to W-band CMOS and SiGe BiCMOS …
