Description
technical field [0001] The present application relates generally to radio frequency (RF) devices, systems and methods. Background technique [0002] Phased array transmit / receive systems are examples of RF systems desired for many applications such as broadcast, radar, space communications, meteorological research, optics, radio frequency (RF) identification systems, and tactile feedback systems. Such a system could also be used for gesture sensing, communication backhaul, and high-speed routing in Wireless Gigabit (WiGig) or other consumer wireless systems. [0003] A phased array system includes an array of antennas in which the relative phase and amplitude of multiple signals transmitted by or received via the antennas can be adjusted. This adjustment can be performed in various parts of the system and equipment, such as RF, intermediate frequency (IF) or baseband (BB) sections, before or after analog-to-digital conversion or digital-to-analog conversion, etc. With prop...
