A D-Band Phased-Array Chain Based on a Tunable Branchline Coupler and a Digitally Controlled Vector Modulator

IEEE Journal of Microwaves
Wireless communication and sensing applications seek higher frequencies to enable higher data rates or more precise localization using a wider modulation bandwidth. Particularly, 6G and autonomous driving research projects focus on the D-band.
