1. A radio frequency (RF) device comprising:
a computer;
a pulses-per-second (PPS) signal source outputting a PPS signal; and
N base units where N is an integer greater than or equal to two, each base unit including:
a differential segmented aperture (DSA) tile including a support board and a two-dimensional (2D) array of electrically conductive tapered projections disposed on the support board with the electrically conductive tapered projections tapering in a direction extending away from the support board, wherein neighboring pairs of the electrically conductive tapered projections form RF pixels; and
at least one RF unit (RFU) having RF connections with the DSA tile to transmit and/or receive RF signals via the RF pixels of the DSA tile and operatively connected to transfer digital data to and/or from the computer;
wherein the RFUs of the N base units are programmed to operate the DSA tiles as a phased RF array with the digital data transferred to and/or from the computer being synchronized using the PPS signal.
