Key receiver circuits for digital beamforming in millimeter-wave imaging
… research, we investigate key components for an active phased array imaging system operating at 77GHz that performs purely digital beamforming. Each element in the phased array has an antenna and processor that measures the phase and amplitude of the received signal. The focus of this thesis is …

Phased array impedance tuning, secure transmission, and nonlinear spatial intermodulation suppression for next-generation radar and communications systems.
… communications signals from the same multi-beam phased array system, using spatial diversity, allows multiple functions to use the same frequency and can alleviate spectral congestion. An issue arises, however in a transmitter array that consists of power amplifiers connected to the antenna …
