Abstract: In this letter, a 6-bit ultra-wideband phase shifter for active phased arrays is presented in 0.18 µm SiGe BiCMOS process. A differential two-stage transformer-based poly-phase quadrature ...
Abstract: A wideband W-band 6-bit vector-sum based active phase shifter which was implemented using a 28-nm RF CMOS process is presented. The proposed phase shifter consists of a differential I/Q ...
