A hierarchical phase shift and delay apparatus enables a large broadband phased-array antenna that is not subject to beam squint. The size of the phased-array antenna both in physical dimension and in number of array elements determines the number of hierarchical delay levels. A method for squint compensation distributes control signal values for phase shift, gain, and time delay for each block. Embodiments of digital squint compensation include phase shift indexers, a plurality of switches coupled to ground taps of a floating strip to adjust the characteristic impedance of a transmission line for fine adjustment; and a hierarchy of tunable squint compensation structures including die-level squint compensation structures coupled to each of the radio frequency chains; and panel-level true time-delay phase shift structures coupled to each of the die-level squint compensation structures. The article of manufacture enables aggregation of sub-arrays which are fabricated to avoid beam squint.
