Abstract :
A phase-locked loop (PLL) array has been developed to perform electronic beam steering at W-band (76-77 GHz) for radar applications. It uses external current injection into the outputs of the charge pump (CP) in the frequency synthesizers to adjust the phase of the voltage control oscillators (VCO) in the PLL array. The measurement array radiation pattern is presented.
