Abstract: A dual-band dual-circularly polarized (dual-CP) multibeam transmit-array (TA) system providing the four-color scheme at both the low- and high-frequency bands is proposed and demonstrated.

Abstract: This paper presents fully integrated 2x2 MIMO dual-band CMOS power amplifiers with a simultaneous multiple PA supply voltage modulation technique using a switched-capacitor (SC)-based single ...
