Abstract:To exploit the >100-GHz spectrum and overcome the attenuation of the wireless channel, a large-scale CMOS phased array is indispensable. However, the size of the array is currently limited by the loss and imbalance of the classic binary distribution network. In addition, since the available chip area shrinks quadratically with the wavelength ( ∝λ2 ), a >100-GHz λ /2-spaced planar array is highly challenging. To solve the above issues, this article presents a D-band, 2-D scalable CMOS planar phased array transmitter (TX) with a precise λ /2 antenna spacing. It employs a traveling-wave LO/IF dis
