The relentless demand for multi-gigabit wireless communication and high-resolution sensing drives rapid innovation in D-band (110–170 GHz) systems. However, realizing efficient and scalable active phased arrays at these frequencies remains challenging due to high cost, interconnect losses, packaging parasitics, and heterogeneous integration constraints. This talk presents a holistic, system-level approach to low-loss D-band phased array integration that unifies circuit, antenna, and packaging co-design. The approach combines optimized beamformer and power-amplifier architectures with low-cost, 2D-scalable, wide-angle scanning antenna arrays. Measured prototype results demonstrate wide-angle beam steering and data transmission rates up to 100 Gb/s.
