Reconfigurable Circuit Design Techniques For Mm Wave Phased Array Radios

Wireless technology is redefining life and fueling socio-economic growth globally due to a dramatic increase in the use of mobile devices and growing number of data-hungry applications. However, the very success of wireless technology is leading to a severe spectrum crunch. Ongoing advances in the device and integrated circuit technology are enabling low-cost phased-array radios that can operate at millimeter-wave (mm-wave) bands as they provide very large bandwidth to meet data-rate demands. Future single-chip solution will require wideband circuits to support multiple mm-wave bands for a higher aggregate data-rate. In addition, low-power consumption and a compact circuit size are desired for battery-limited mobile radios as the power consumption and area of phased-array increases with the number of array elements.
