The design of a fully-integrated multiband tunable linearized CMOS active analog phase shifter with active loss compensation that has broadband signal transmission and provides multiband phase shifting and that allows for broadband distortion reduction is presented. The S21 differential power gain peaks at 7 dB and then rolls off to a unity gain bandwidth of 11.5 GHz. The simulated phase S21 shift tuning performance is better than 50 degrees at multiple bands of 2.4 GHz and 5.8 GHz. The simulated linearized phase shifter IIP3 show a 10 dB improvement. Simulation results show that the co-design of the active analog phase shifter with on-chip loop antenna in both transmit and receive path has phase S21 shift tuning performance which is better than 50 degrees and is compared to a stand alone on-chip loop antenna S21 phase performance. The CMOS active analog phase shifter was fabricated using the 0.13 mum CMOS technology and has a total silicon chip area of 1.887times0.795 mm2.
